Functional description

1.1 Overview
NINA-B1 series modules are small stand-alone Bluetooth® low energy modules featuring Bluetooth 5,
a powerful Arm® Cortex®-M4 with FPU, and state-of-the-art power performance. The embedded low
power crystal in NINA-B1 minimizes power consumption, thus extending the battery life.
NINA-B1 is delivered with u-connectXpress software that provides support for u-blox Bluetooth low
energy Serial Port Service, GATT client and server, beacons, NFC™, and simultaneous peripheral andcentral roles – all configurable from a host by using AT commands.
NINA-B1 offers full flexibility for customers who prefer to add their application to run on the built-in
Cortex-M4 with FPU. With 512 kB flash and 64 kB RAM, it offers the best-in-class capacity forcustomer applications running on top of the Bluetooth low energy stack using SDK from Nordic
Semiconductor or Arm® Mbed™. Additionally, NFC and interfaces such as SPI, I2C, and I2S areavailable, and features like Bluetooth Mesh, AirFuel, and Apple HomeKit are also supported.
NINA-B112 comes with an internal antenna and NINA-B111 has a pin for use with an external antenna.
The internal PIFA antenna is specifically designed for the small NINA-B1 form factor and provides anextensive range of more than 300 m, independent of ground plane and component placement.
The module is globally certified for use with the internal antenna or a range of external antennas. This
reduces time and effort for customers integrating NINA-B1 in their designs.

Nordic SDK, or embedded Wirepas Mesh development environment in NINA-B1.

1.6.2.1 Nordic SDK
The Nordic nRF5 SDK provides a rich and well tested software development environment for nRF52based devices. It includes a broad selection of drivers, libraries, and example applications. It also
includes other radio stacks, although NINA-B1 series modules are only certified for use with the S132
Bluetooth Low Energy SoftDevice. Customers that want to use a proprietary 2.4 GHz radio protocol
should contact u-blox support.

1.6.2.2 Arm Mbed OS
Arm Mbed OS is an open-source embedded operating system designed specifically for the "things" in
the “Internet of Things”. It includes all features to develop a connected product, including security,connectivity, an RTOS, and drivers for sensors and I/O devices. The NINA-B1 series fully supports
Mbed OS 5.

1.6.2.3 Wirepas connectivity software
NINA-B1 can also be used together with the Wirepas software stack. The stack enables the use of
NINA-B1 modules in large-scale mesh environments.
Wirepas is third-party connectivity software licensed from Wirepas.
For more information about the Wirepas connectivity software, contact your local u-blox support
team or Wirepas directly.

1.7 Bluetooth device address
Each NINA-B1 module is preprogrammed with a unique 48-bit Bluetooth device address. If thememory of the module is corrupted or lost, the address can be recovered from the data matrix barcode
printed on the module label. For more information about Bluetooth device address recovery, see also
the NINA-B1 system integration manual [1].

2Interfaces

2.1 Power management
2.1.1 Module supply input (VCC)
NINA-B1 series uses integrated step-down converters to transform the supply voltage presented at
the VCC pin into a stable system voltage. This means that NINA-B1 modules are compatible for use
in battery powered designs – without the use of an additional voltage converter.
The modules support two on-board converters:• A low-dropout (LDO) converter• A DC/DC buck converter
The module automatically switches between these converters to suit the prevailing current
consumption. The DC/DC converter is more efficient under high loads when the radio is active, while
the LDO converter is better suited for power saving modes.

2.1.2 Digital I/O interfaces reference voltage (VCC_IO)
All modules in the NINA series generally provide an additional voltage supply input for setting the I/O
voltage level. In NINA-B1 series modules, the I/O voltage level is similar to the supply voltage and
VCC_IO is internally connected to the supply input. Therefore, only a single supply voltage is needed
for NINA-B1, which makes it ideal for battery powered designs.

☞

The supply arrangements can vary in other modules in the NINA series. A design that is pin
compatible with other NINA-series modules should keep the VCC and VCC_IO supply rails
separate.

2.2 RF antenna interfaces
2.2.1 2.4 GHz Bluetooth low energy (ANT)NINA-B111 and B112 have their own 2.4 GHz antenna solutions:• NINA-B111 modules are equipped with an antenna pin (ANT) with a nominal characteristic
impedance of 50 Ω. This pin can be connected to an on-board antenna, or antenna connector,
using a controlled impedance trace. For more information, see also the NINA-B1 system
integration manual [1].
• NINA-B112 modules use an integrated antenna solution; no additional components are required.
The ANT pin is internally disconnected on these models.

2.2.2 Near Field Communication (NFC)
NINA-B1 series modules include a Near Field Communication interface that is capable of operating as
a 13.56 MHz NFC tag at a bit rate of 106 kbps.
As an NFC tag, data can be read from or written to NINA-B1 using an NFC reader. However, NINA-B1
modules are not capable of reading other tags or initiating NFC communications.
The NFC interface can be used to wake the module from sleep mode, which means that the module
can be kept in the deepest power save mode and still wake up properly to react to an NFC field.
Two pins are available for connecting to an external NFC antenna: NFC1 and NFC2. See also the
NINA-B1 system integration manual [1].

2.3 System functions
2.3.1 Power modes
NINA-B1 series modules use power-efficient LDO and DC/DC regulators and can operate in different
power modes and configurations. Consequently, specific parts of the module can be powered off when
they are not needed and complex wake-up events can be generated from different external andinternal inputs.

2.3.1.1 System OFF mode
System OFF mode is the deepest power saving mode. It is in this mode that NINA-B1 modules sleep,so that all functionality is stopped to ensure minimum power consumption.
An external event is required to wake up the module from sleep in the system OFF mode. Although
the module always reboots after waking up from the system OFF mode, some non-volatile registers
in RAM can be configured so that they remain intact during and after going to the system OFF mode.
You can switch on or reboot NINA-B1 modules in any of the following ways:••••

Module reset. See also Module reset.
Programmable digital or analog sensor event. In response to a rising voltage level flag from ananalog comparator pin, or similar.
NFC field detection
5 V supply to the VBUS pin (USB interface plug in)

2.3.1.2 System ON mode
When powered on or reset, NINA-B1 modules return to the default configuration set by the application
software flashed in the module. In System ON mode all functional blocks and system peripherals areavailable in either RUN mode or in IDLE mode. The software configuration and the application under
execution determines the mode of operation.
System ON mode has two optional sub-power modes, Constant Latency and Low-Power. Designers
can choose which sub-power mode is most appropriate for the application, but only one can be
enabled at any given time. These modes are active when the CPU or other peripherals are idling.

2.3.1.2.1 Constant latency
You can configure the CPU and other programmable peripherals to use minimal resources. The
module can be turned on from sleep (System OFF mode) with constant and predictable CPU wakeup
latency, but not without introducing some degradation in the power efficiency.

2.3.1.2.2 Low-PowerThe module draws least power in the (default) Low-power mode of NINA-B1 modules. The automatic
power management system in the Nordic chip limits the minimum power consumption. The module
is turned on from sleep with varying CPU wakeup latency and peripherals tasks.

2.3.2 Module reset
A reset on NINA-B1 module can be triggered with following different ways:
•
•
•
•
•
•

Pin reset: when a low level on the RESET_N input pin. If used, the software should configure apull-up on this pin. The low-level state causes an “external” or “hardware” reset of the module.
Power-on reset: when VCC rises above the power-on threshold.
Wake from System OFF: when module wakes from System OFF mode.
Soft reset: when using the reset control register.
Watchdog timer (WDT) reset: when module watchdog timer times out.
Brownout reset: when VCC drops below brownout threshold voltage

2.3.3 CPU and memory
The Nordic Semiconductor nRF52832 chip in the NINA-B1 series modules includes a powerful Arm®
Cortex®-M4 with FPU processor has 32-bit instruction set. The processor works with a superset of 16
and 32-bit instructions (Thumb-2) at 64 MHz clock speed. It can use up to 37 interrupt vectors and 3priority bits. The nRF52832 chip has 512 kB of flash and 64 KB of RAM for code and data storage.

2.3.4 Direct Memory Access
All interfaces described in this data sheet support Direct Memory Access (DMA) to move any data
generated from the interface directly into the RAM, without involving the CPU. This ensures fluent
operation of the CPU with minimal need for interruption. To reduce the overall power consumption,
DMA should be used as often as possible.

2.3.5 Programmable Peripheral Interconnect
The Nordic Semiconductor nRF52832 chip in the NINA-B1 series modules includes a programmableperipheral interconnect (PPI) switch matrix that connects various control signals between different
interfaces and system functions. The switch allows most interfaces to bypass the CPU when
triggering a system function. In this way, an incoming data packet can trigger a counter on the fallingvoltage level on an ADC or toggle a GPIO – without having to send an interrupt to the CPU. Thisfunctionality facilitates the development of smart, power-efficient applications that wake up the CPU
only when it is necessary.

2.3.6 Real Time Counter (RTC)
A key system feature of the module is the Real Time Counter (RTC). This counter can generate andsend multiple interrupts and events to the internal and external hardware blocks, CPU and radio. The
events can be precisely timed and range from microseconds up to hours and leveraged for periodic
Bluetooth LE advertising and other applications – without involving the CPU. The RTC can be operated
in the active and standby modes.

2.4 Serial interfaces
NINA-B1 modules provide the following serial communication interfaces:••••

1x UART interfaces: 4-wire universal asynchronous receiver/transmitter
3x SPI interfaces: Up to four serial peripheral interfaces can be used simultaneously
2x I2C interfaces: Inter-Integrated Circuit (I2C) interface for communication with digital sensors
1x I2S interface: Used to communicate with external audio devices☞

Most digital interface pins on the module are shared between the digital, analog interfaces and
GPIOs. Unless otherwise stated, all functions can be assigned to any pin that is not alreadyoccupied.

☞

Two of the SPI interfaces share common hardware with the I2C interfaces. These interfaces
cannot be used simultaneously. If both I2C interfaces are in use only one SPI interface is available.

2.4.1 Asynchronous serial interface (UART)The 4-wire UART interface supports hardware flow control and baud rates up to 1 Mbps. Other
characteristics of the UART interface are listed below:
•

•
•
•
•

•
•

Pin configuration:o TXD, data output pin
o RXD, data input pin
o RTS, Request To Send, flow control output pin (optional)o CTS, Clear To Send, flow control input pin (optional)
Hardware flow control or no flow control is supported.
Power saving indication available on the hardware flow control output (RTS pin): The line is driven
to the OFF state when the module is not ready to accept data signals.
Programmable baud rate generator allows most industry standard rates up to 1 Mbps.
Frame format configuration:o 8 data bits
o Even or no-parity bito 1 stop bit
Default frame configuration is 8N1, meaning eight (8) data bits, no (N) parity bit, and one (1) stopbit.
Frames are transmitted in such a way that the least significant bit (LSB) is transmitted first.

2.4.2 Serial peripheral interface (SPI)NINA-B1 supports up to three Serial Peripheral Interfaces with serial clock frequencies up to 8 MHz.
Characteristics of the SPI interfaces are listed below:
•

•

•
•

Pin configuration in master mode:o SCLK, Serial clock output
o MOSI, Master Output Slave Input data lineo MISO, Master Input Slave Output data line
Pin configuration in slave mode:o SCLK, Serial clock input
o MOSI, Master Output Slave Input data lineo MISO, Master Input Slave Output data line
Both master and slave modes are supported on all the interfaces.
The serial clock supports both normal and inverted clock polarity (CPOL) and data should be
captured on rising or falling clock edge (CPHA).

2.4.3 Inter-Integrated Circuit interface (I2C)
The Inter-Integrated Circuit (I2C) interfaces can be used to transfer and/or receive data on a 2-wirebus network. The NINA-B1 modules can operate as both master and slave on the I2C bus using
standard (100 kbps), fast (400 kbps), and 250 kbps transmission speeds. The interface supports
clock stretching, which allows NINA-B1 to temporarily pause any I2C communications. Up to 127
individually addressable I2C devices can be connected to the same two signals.
•

Pin configuration:o SCL, clock output in master mode, input in slave modeo SDA, data input/output pin

This interface requires external pull-up resistors to work properly in the master mode. See also I2C
pull-up resistor values. The pull-up resistors are also required in slave mode and these should beplaced at the master end of the interface.

2.4.4 Inter-IC Sound interface (I2S)
The Inter-IC Sound (I2S) interface can be used to transfer audio sample streams between NINA-B1
and external audio devices such as codecs, DACs, and ADCs. It supports original I2S and left or rightaligned interface formats in both master and slave modes.
•

Pin configuration:o MCK, master clocko LRCK, left right/word/sample clock
o SCK, serial clock
o SDIN, serial data ino SDOUT, serial data out

The master side of an I2S interface always provides the LRCK and SCK clock signals, but some masterdevices cannot generate a MCK clock signal. NINA-B1 can supply a MCK clock signal in both masterand slave modes to provide to those external systems that cannot generate their own clock signal.
The two data signals - SDIN and SDOUT allow for simultaneous bi-directional audio streaming. Theinterface supports 8, 16, and 24-bit sample widths with up to 48 kHz sample rate.

2.5 Digital interfaces
2.5.1 Pulse Width Modulation (PWM)
NINA-B1 modules provide up to 16 independent PWM channels that can be used to generate complex
waveforms. The waveforms can be used to control motors, dim LEDs, or as audio signals if connectedto the speakers. Duty-cycle sequences may be stored in the RAM to be chained and looped into
complex sequences without CPU intervention. Each channel uses a single GPIO pin as output.

2.5.2 Pulse Density Modulation (PDM)
The pulse density modulation interface is used to read signals from external audio frontends like
digital microphones. It supports single or dual-channel (left and right) data input over a single GPIO
pin. It supports up to 16 kHz sample rate and 16-bit samples. The interface uses the DMA toautomatically move the sample data into RAM without CPU intervention. The interface uses two
signals - CLK to output the sample clock and DIN to read the sample data.

2.5.3 Quadrature Decoder (QDEC)
The quadrature decoder is used to read quadrature encoded data from mechanical and opticalsensors in the form of digital waveforms. Quadrature encoded data is often used to indicate rotationof a mechanical shaft in either a positive or negative direction. The QDEC uses two inputs - PHASE_A
and PHASE_B, and an optional LED output signal. The interface has a selectable sample periodranging from 128 µs to 131 ms.

2.6 Analog interfaces
8 out of the 19 digital GPIOs can be multiplexed to analog functions. The following analog functions
are available:•••

1x 8-channel ADC
1x Analog comparator*
1x Low-power analog comparator**Only one comparator can be used at any given point in time.

2.6.1 Analog to Digital Converter (ADC)The Analog to Digital Converter (ADC) is used to sample analog voltage on the analog function enabledpins of the NINA-B1. Any of the 8 analog inputs can be used. Characteristics of the ADC include:
•
•
•
•
•
•
•
•

Full swing input range of 0 V to VCC.
8/10/12-bit resolution
14-bit resolution while using oversampling
Up to 200 kHz sample rate
Single shot or continuous sampling
Two operation modes: Single-ended or Differential
Single-ended mode:o A single input pin is used
Differential mode:o Two inputs are used and the voltage level difference between them is sampled

If the sampled signal level is much lower than the VCC, it is possible to lower the input range of the
ADC to better encompass the wanted signal and achieve higher resolution. Continuous sampling canbe configured to sample at a configurable time interval, or at different internal or external events,
without CPU involvement.

2.6.2 Comparator
The analog comparator compares the analog voltage on one of the analog enabled pins in NINA-B1
with a highly configurable internal or external reference voltage. Events can be generated anddistributed to the rest of the system when the voltage levels cross. Further characteristics of thecomparator include:
•
•
•
•
•

Full swing input range of 0 V to VCC
Two operation modes: Single-ended or Differential
Single-ended mode: A single reference level or an upper and lower hysteresis selectable from a 64level reference ladder with a range from 0 V to VREF, as described in Table 3.
Differential mode: Two analog pin voltage levels are compared, optionally with a 50 mV hysteresis
Three selectable performance modes - High speed, balanced, or power save

For a comparison of the various analog comparator options, see also Analog comparator.

2.6.3 Low power comparator
In addition to the power save mode available for the comparator, there is a separate low powercomparator available on the NINA-B1 module. This allows for even lower power operation, at a slightly
lower performance and with less configuration options. Characteristics of the low power comparator
include:••••Full swing input range of 0 to VCC
Two operation modes - Single-ended or Differential
Single-ended mode:o The reference voltage LP_VIN is selected from a 15-level reference ladder
Differential mode:oo

GPIO_24 or GPIO_25 is used as reference voltage
LP_VIN can be used to wake the system from sleep (system OFF mode)

Table 3 shows the analog pin options. To compare the electrical specifications for the different analog
comparator options, see also Analog comparator.
Since the run current of the low power comparator is very low, it can be used as an analog trigger towake up the CPU when the module sleeps in the System OFF mode. See also Power modes.

2.7 GPIO
NINA-B1 series modules have a versatile pinout. With no dedicated analog or digital interfaces, allmodule interfaces and functions must be allocated to a specific GPIO pin. This is configured in thesoftware.
NINA-B1 modules have 19 GPIO pins. 8 of these are analog-enabled pins that can be assigned to ananalog function.
In addition to the serial interfaces, Table 4 describes the analog digital and functions that can be
assigned to a GPIO pin. Two of the GPIOs are optional NFC.

2.7.1 Drive strength
All GPIO pins are normally configured for low current consumption. Using this standard low-drive
strength, any pin configured as an output can only source or sink a certain amount of current. If thetiming requirements of any digital interface cannot be met, or if an LED requires more current than
the available amount of current in this mode, a high drive strength mode can be configured in thesoftware so the digital output can draw more current. See also Digital pins.

☞

Some GPIOs can introduce noise in the system when they are configured for high drive strength
or connected to a signal with a switching speed higher than 10 kHz. See also Pin assignment.

2.8 Debug interfaces
2.8.1 SWD
NINA-B1 series modules provide an SWD interface for flashing and debugging. The interface consistsof two pins: SWDCLK and SWDIO.

2.8.2 Trace – Serial Wire Output
A serial trace option is available on the NINA-B1 series modules as an additional pin, SWO. The Serial
Wire Output (SWO) is used to:•••

Support printf style debugging
Trace OS and application events
Emit diagnostic system information

A debugger that supports Serial Wire Viewer (SWV) is required.

2.9 u-connectXpress software features☞

This section describes the available features when using the u-connectXpress software. See theu-connectXpress AT commands manual [3] and u-connectXpress software user guide [6].

2.9.1 u-blox Serial Port Service (SPS)The serial port service feature enables serial port emulation over Bluetooth low energy.

2.9.2 Module power-on
You can switch on or reboot the NINA-B1 modules in one of the following ways:••

Rising edge on the VCC pin to a valid supply voltage
Issuing a reset of the module. See also Module reset.

An event to wake up from the sleep mode to the active mode can be triggered by:••

Programmable digital or analog sensor event, e.g., rising voltage level on an analog comparator pin
Detecting an NFC field

While waking up from the standby mode to active mode, an event can also be triggered by:•••

The on-board Real Time Counter (RTC)
The radio interface
Detection of an NFC field

NINA-B1 series - Data sheet

2.9.3 Module power off
There is no dedicated pin to power off the NINA-B1 modules. You can configure any GPIO pin to enteror exit Sleep mode, which essentially powers down the module.
An under-voltage (brown-out) shutdown occurs on the NINA-B1 modules when the VCC supply drops
below the operating range minimum limit. If this occurs, it is not possible to store the current
parameter settings in the module’s non-volatile memory.

2.9.4 Power modes
The NINA-B1 series modules are power efficient devices capable of operating in different powersaving modes and configurations. Different sections of the module can be powered off when notneeded and complex wake-up events can be generated from different external and internal inputs.
The radio part of the module operates independently from the CPU. The three main power modes are:•••ActiveStandby
Sleep

Depending on the application, the module should spend most of its time in either standby or sleep
mode to minimize current consumption.

2.9.4.1 Standby modeStandby mode is one of the power saving modes in NINA-B1 modules that essentially powers down
the module but keeps the system RAM and configurations intact. It also allows for complex,
autonomous power-up events including periodic RTC events and radio events.
The following events can be used to bring the module out of the standby mode:••

Internal wake-up events from the RTC, radio, NFC and so on.
Analog or digital sensor events (programmable voltage level or edge detection)

During standby mode, the module is clocked at 32.768 kHz, which is generated by an internal RCoscillator.

2.9.4.2 Sleep mode
Sleep mode is the deepest power saving mode of NINA-B1 modules. During sleep mode, allfunctionality is stopped to ensure minimum power consumption. The module needs an external eventin order to wake up from the sleep mode. The module will always reboot after waking up from the sleep
mode; however, different sections of the RAM can be configured to remain intact during and after
going to the sleep mode.
The following events can be used to wake up the module out of the sleep mode:•••

External event on a digital pin
External analog event on a low power comparator pin
Detection of an NFC field

When using the u-connectXpress software, the module can be manually switched on or off with proper
storage of the current settings using the UART DSR pin.
The module can be programmed to latch the digital values present at its GPIO pins during sleep. The
module will keep the values latched, and a change of state on any of these pins will trigger a wake-up
to active mode.

NINA-B1 series - Data sheet

2.9.5 Module reset
The NINA-B1 modules can be reset using one of the following ways:••

Low level on the RESET_N input pin, normally kept high using an internal pull-up. This causes an“external” or “hardware” reset of the module. The current parameter settings are not saved in themodule’s non-volatile memory and a proper network detach is not performed.
With the NINA-B1 modules, using the AT+CPWROFF command. This causes an “internal” or“software” reset of the module. The current parameter settings are saved in the module’s nonvolatile memory.

2.9.6 System status signals
The RED, GREEN and BLUE pins are used to signal the system status according to Table 5. They are
active low and are intended to be routed to an RGB LED.

2.9.7 System control signals
The following input signals are used to control the system:• RESET_N is used to reset the system. See also Module reset.
• If SWITCH_2 is driven low during start up, the UART serial settings are restored to their default
values.
• SWITCH_2 can be used to open a Bluetooth LE connection with a peripheral device.
• If both SWITCH_1 and SWITCH_2 are driven low during start up, the system enters the bootloader
mode.
• If both SWITCH_1 and SWITCH_2 are driven low during start up and held low for 10 seconds, thesystem exits the bootloader mode and restore all settings to their factory default.

2.9.8 UART signals
In addition to the normal RXD, TXD, CTS, and RTS signals, the u-connectXpress software adds the
DSR and DTR pins to the UART interface. Note that they are not used as originally intended, but tocontrol the state of the NINA module. For example, depending on the current configuration.
The DSR pin can be used to:• Enter command mode
• Disconnect and/or toggle connectable status• Enable/disable the rest of the UART interface
Enter/wake up from sleep mode
The DTR pin can be used to indicate:••••

• The outline of NINA-B111 ends at the dotted line, where the antenna area of NINA-B112 begins.
• Most of the digital or analog functions shown here and described in this data sheet can be freely
assigned to any GPIO pin. Analog functions are limited to analog capable pins.
• Signals that are highlighted in red are not freely assignable but are locked to a specific pin.
• GPIO pins 16, 17, 18 and 20 are connected to the pins located close to the radio part of the RF chip.
Digital noise on these pins can reduce the radio sensitivity.
If you use the u-connectXpress software, refer to the Pin assignment in the u-connectXpress
software.

A = Analog function capable pin
Figure 3: NINA-B1 series pin assignment (top view)⚠

Do not apply an NFC field to the NFC pins when they are configured as GPIOs. Applying the field inthese circumstances can cause permanent damage to the module. When driving different logic
levels on these pins in GPIO mode a small current leakage is expected. Ensure that NFC pins are
set to the same logic level before entering any of the power saving modes. See also RESET_N pin.

8.2 Moisture sensitivity levels⚠

In accordance with the IPC/JEDEC J-STD-020 standard, NINA-B1 series modules are tested,classified, and rated as Moisture Sensitive Devices (MSD). The Moisture Sensitivity Level (MSL)
relates to the required packaging and handling precautions.

NINA-B1 series modules are rated at MSL level 4.
For more information about the moisture sensitivity levels, labeling, and storage of u-blox chips,
modules, and antennas, see the Packaging information reference [2].

☞For general information about MSL, download the joint IPC/JEDEC J-STD-020 standard fromwww.jedec.org.

8.3 Reflow soldering
Reflow profiles are selected according to u-blox recommendations. For more information, see also the
NINA-B1 system integration manual [1].

⚠

Failure to observe these recommendations can result in severe damage to the device.

8.4 ESD precautions⚠

NINA-B1 series modules contain highly sensitive electronic circuitry and areElectrostatic Sensitive Devices (ESD). Handling NINA-B1 series modules
without proper ESD protection may destroy or damage them permanently.

NINA-B1 series modules are electrostatic sensitive devices (ESD) and require
special ESD precautions typically applied to the ESD sensitive components.
See also. Maximum ESD ratings .
Proper ESD handling and packaging procedures must be applied throughout the processing, handlingand operation of any application that incorporates the NINA-B1 series module. Failure to observe
these recommendations can result in severe damage to the device.
Observance of ESD precautions is particularly important when handling the application board on towhich the module is mounted. See also the NINA-B1 system integration manual [1].
