Description
The X-NUCLEO-WB05KN1 expansion board provides Bluetooth® Low Energy
connectivity for developer applications and can be plugged into an STM32 Nucleo
development board (for example NUCLEO-U575ZI-Q) through its ARDUINO® UnoV3 connectors.
The expansion board features Bluetooth® v5.4 compliant and FCC‑certified
STM32WB05KN. This SoC manages the complete Bluetooth® Low Energy stack andprotocols on its Arm® Cortex®‑M0+ core and programmable flash memory.
STM32WB05KN supports central and peripheral modes and increased transfer rates
with data length extension (DLE).
X-NUCLEO-WB05KN1 interfaces with the STM32 Nucleo microcontroller via UART(default) with and without hardware flow control. Full duplex SPI with an interrupt line
is also available. The firmware loaded on the module defines the host interface and,to modify it, simply change the firmware without modifying the hardware.

Ordering information
To order the X-NUCLEO-WB05KN1 expansion board, refer to Table 1. For a detailed description, refer to its user
manual on the product web page. Additional information is available from the datasheet and reference manual of
the target STM32.

Product marking
The stickers located on the top or bottom side of all PCBs provide product information:•First sticker: product order code and product identification, generally placed on the main board featuring
the target device.
Example:Product order code
Product identification•

Second sticker: board reference with revision and serial number, available on each PCB.
Example:MBxxxx-Variant-yzz
syywwxxxxx

On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board
reference, “Variant” (optional) identifies the mounting variant when several exist, “y” is the PCB revision, and “zz”
is the assembly revision, for example B01. The second line shows the board serial number used for traceability.
Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not
responsible for any consequences resulting from such use. In no event will ST be liable for the customer using
any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision
to use these engineering samples to run a qualification activity.
“ES” or “E” marking examples of location:••

On the targeted STM32 that is soldered on the board (for an illustration of STM32 marking, refer to theSTM32 datasheet Package information paragraph at the www.st.com website).
Next to the evaluation tool ordering part number that is stuck, or silk-screen printed on the board.

Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a “U” marking option at the end of the standard part number
and is not available for sales.
To use the same commercial stack in their applications, the developers might need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
