For details, see `GPIO Header 2`_. - A 4-bit DIP switch used to configure the functionality of selected GPIOs of ESP32. For details see `Function Switch`_. - Two LEDs to show the status of UART transmission. - The FT2232H chip serves as a multi-protocol USB-to-serial bridge which can be programmed and controlled via USB to provide communication with ESP32.

FT2232H also features USB-to-JTAG interface which is available on channel A of the chip, while USB-to-serial is on channel B. The FT2232H chip enhances user-friendliness in terms of application development and debugging. See `ESP32-Ethernet-Kit V1.2 Ethernet board (A) schematic`_. - USB interface. Power supply for the board as well as the communication interface between a computer and the board. - Power On/Off Switch. Toggling the switch to **5V0** position powers the board on, toggling to **GND** position powers the board off. - The 5 V power supply interface can be more convenient when the board is operating autonomously (not connected to a computer). - This red LED turns on when power is supplied to the board, either from USB or 5 V Input. - Provided DC 5 V to 3.3 V conversion, output current up to 2 A. - A pair male and female header pins for mounting the `PoE board (B)`_ - The physical layer (PHY) connection to the Ethernet cable is implemented using the `IP101GRI `_ chip.

The connection between PHY and ESP32 is done through the reduced media-independent interface (RMII), a variant of the media-independent interface `(MII) `_ standard. The PHY supports the IEEE 802.3/802.3u standard of 10/100 Mbps. - Ethernet network data transmission port. - The Magnetics are part of the Ethernet specification to protect against faults and transients, including rejection of common mode signals between the transceiver IC and the cable. The magnetics also provide galvanic isolation between the transceiver and the Ethernet device. - Two LEDs (green and red) that respectively indicate the "Link" and "Activity" statuses of the PHY. - Download button. Holding down **BOOT** and then pressing **EN** initiates Firmware Download mode for downloading firmware through the serial port. - Reset button. - This header provides six unpopulated through-hole solder pads connected to spare GPIOs of ESP32. For details, see `GPIO Header 1`_. .. note:: Automatic firmware download is supported.

If following steps and using software described in Section `Start Application Development`_, users do not need to do any operation with BOOT button or EN button. PoE Board (B) This board coverts power delivered over the Ethernet cable (PoE) to provide a power supply for the Ethernet board (A). The main components of the PoE board (B) are shown on the block diagram under `Functionality Overview`_. The PoE board (B) has the following features: To take advantage of the PoE functionality the **RJ45 Port** of the Ethernet board (A) should be connected with an Ethernet cable to a switch that supports PoE. When the Ethernet board (A) detects 5 V power output from the PoE board (B), the USB power will be automatically cut off. .. figure:: ../../../_static/esp32-ethernet-kit-b-v1.0-layout.png :align: center :scale: 80% :alt: ESP32-Ethernet-Kit - PoE board (B) :figclass: align-center ESP32-Ethernet-Kit - PoE board (B) layout (click to enlarge) .. list-table:: Table PoE board (B) :widths: 40 150 :header-rows: 1 - Description - Four female (left) and four male (right) header pins for connecting the PoE board (B) to :ref:`Ethernet board (A) `.

The pins on the left accept power coming from a PoE switch. The pins on the right deliver 5 V power supply to the Ethernet board (A). - Optional power supply (26.6 ~ 54 V) to the PoE board (B). .. _get-started-esp32-ethernet-kit-v1.2-setup-options: Setup Options This section describes options to configure the ESP32-Ethernet-Kit hardware. Function Switch When in On position, this DIP switch is routing listed GPIOs to FT2232H to provide JTAG functionality. When in Off position, the GPIOs may be used for other purposes. DIP SW GPIO Pin 1 GPIO13 2 GPIO12 3 GPIO15 4 GPIO14 RMII Clock Selection The ethernet MAC and PHY under RMII working mode need a common 50 MHz reference clock (i.e., RMII clock) that can be provided either externally, or generated from internal ESP32 APLL (not recommended). .. note:: For additional information on the RMII clock selection, please refer to `ESP32-Ethernet-Kit V1.2 Ethernet board (A) schematic`_, sheet 2, location D2.

RMII Clock Sourced Externally by PHY """""""""""""""""""""""""""""""""""" By default, the ESP32-Ethernet-Kit is configured to provide RMII clock for the IP101GRI PHY's 50M_CLKO output. The clock signal is generated by the frequency multiplication of 25 MHz crystal connected to the PHY. For details, please see the figure below. .. figure:: ../../../_static/esp32-ethernet-kit-rmii-clk-from-phy.png :align: center :scale: 80% :alt: RMII Clock from IP101GRI PHY :figclass: align-center RMII Clock from IP101GRI PHY Please note that the PHY is reset on power up by pulling the RESET_N signal down with a resistor. ESP32 should assert RESET_N high with GPIO5 to enable PHY. Only this can ensure the power-up of system. Otherwise ESP32 may enter download mode (when the clock signal of REF_CLK_50M is at a high logic level during the GPIO0 power-up sampling phase). RMII Clock Sourced Internally from ESP32's APLL """"""""""""""""""""""""""""""""""""""""""""""" Another option is to source the RMII Clock from internal ESP32 APLL, see figure below.

The clock signal coming from GPIO0 is first inverted, to account for transmission line delay, and then supplied to the PHY. .. figure:: ../../../_static/esp32-ethernet-kit-rmii-clk-to-phy.png :align: center :scale: 80% :alt: RMII Clock from ESP Internal APLL :figclass: align-center RMII Clock from ESP Internal APLL To implement this option, users need to remove or add some RC components on the board. For details please refer to `ESP32-Ethernet-Kit V1.2 Ethernet board (A) schematic`_, sheet 2, location D2. Please note that if the APLL is already used for other purposes (e.g., I2S peripheral), then you have no choice but use an external RMII clock. GPIO Allocation This section describes allocation of ESP32 GPIOs to specific interfaces or functions of the ESP32-Ethernet-Kit. IP101GRI (PHY) Interface The allocation of the ESP32 (MAC) pins to IP101GRI (PHY) is shown in the table below.

.. _get-started-esp-wrover-kit-v3-setup-options: Setup Options There are five jumper blocks available to set up the board functionality. The most frequently required options are listed in the table below. Header Jumper Setting Description of Functionality JP7 |jp7-ext_5v| Power ESP-WROVER-KIT via an external power supply JP7 |jp7-usb_5v| Power ESP-WROVER-KIT via USB JP8 |jp8| Enable JTAG functionality JP11 |jp11-tx-rx| Enable UART communication JP14 |jp14| Enable RTS/CTS flow control for serial communication Allocation of ESP32 Pins Some pins/terminals of ESP32 are allocated for use with the onboard or external hardware. If that hardware is not used, e.g., nothing is plugged into the Camera (JP4) header, then these GPIOs can be used for other purposes. Some of the pins, such as GPIO0 or GPIO2, have multiple functions and some of them are shared among onboard and external peripheral devices. Certain combinations of peripherals cannot work together.

For example, it is not possible to do JTAG debugging of an application that is using SD card, because several pins are shared by JTAG and the SD card slot. In other cases, peripherals can coexist under certain conditions. This is applicable to, for example, LCD screen and SD card that share only a single pin GPIO21. This pin is used to provide D/C (Data/Control) signal for the LCD as well as the CD (Card Detect) signal read from the SD card slot. If the card detect functionality is not essential, then it may be disabled by removing R167, so both LCD and SD may operate together. For more details on which pins are shared among which peripherals, please refer to the table in the next section. Main I/O Connector/JP1 The JP1 connector consists of 14x2 male pins whose functions are shown in the middle two "I/O" columns of the table below.

ESP-WROVER-KIT V4.1 Getting Started Guide This guide shows how to get started with the ESP-WROVER-KIT V4.1 development board and also provides information about its functionality and configuration options. What You Need You can skip the introduction sections and go directly to Section `Start Application Development`_. Overview ESP-WROVER-KIT is an ESP32-based development board produced by `Espressif `_. ESP-WROVER-KIT features the following integrated components: - ESP32-WROVER-E module - LCD screen - microSD card slot Another distinguishing feature is the embedded FTDI FT2232HL chip, an advanced multi-interface USB bridge. This chip enables to use JTAG for direct debugging of ESP32 through the USB interface without a separate JTAG debugger. ESP-WROVER-KIT makes development convenient, easy, and cost-effective. Most of the ESP32 I/O pins are broken out to the board's pin headers for easy access. .. note:: ESP32's GPIO16 and GPIO17 are used as chip select and clock signals for PSRAM.

By default, the two GPIOs are not broken out to the board's pin headers in order to ensure reliable performance.

. list-table:: :widths: 25 75 :header-rows: 1 - Description - The FT2232HL chip serves as a multi-protocol USB-to-serial bridge which can be programmed and controlled via USB to provide communication with ESP32. FT2232HL also features USB-to-JTAG interface which is available on channel A of the chip, while USB-to-serial is on channel B. The FT2232HL chip enhances user-friendliness in terms of application development and debugging. See `ESP-WROVER-KIT V4.1 schematic`_. - External precision 32.768 kHz crystal oscillator serves as a clock with low-power consumption while the chip is in Deep-sleep mode. - Zero-ohm resistor intended as a placeholder for a current shunt, can be desoldered or replaced with a current shunt to facilitate the measurement of ESP32's current consumption in different modes. - This ESP32 module features 64-Mbit PSRAM for flexible extended storage and data processing capabilities. - Four red LEDs connected to the GPIO pins of FT2232HL.

Intended for future use. - Serial port. The serial TX/RX signals of FT2232HL and ESP32 are broken out to the inward and outward sides of JP2 respectively. By default, these pairs of pins are connected with jumpers. To use ESP32's serial interface, remove the jumpers and connect another external serial device to the respective pins. - By default, ESP32 uses its SPI interface to access flash and PSRAM memory inside the module. Use these pins to connect ESP32 to another SPI device. In this case, an extra chip select (CS) signal is needed. Please note that the voltage of this interface is 3.3 V. - Serial port flow control signals: the pins are not connected to the circuitry by default. To enable them, short the respective pins of JP14 with jumpers. - JTAG interface. JTAG signals of FT2232HL and ESP32 are broken out to the inward and outward sides of JP2 respectively. By default, these pairs of pins are disconnected. To enable JTAG, short the respective pins with jumpers as shown in Section `Setup Options`_.

- USB interface. Power supply for the board as well as the communication interface between a computer and the board. - Reset button. - Download button. Holding down **Boot** and then pressing **EN** initiates Firmware Download mode for downloading firmware through the serial port. - Power On/Off Switch.

If that hardware is not used, e.g., nothing is plugged into the Camera (JP4) header, then these GPIOs can be used for other purposes. Some of the pins, such as GPIO0 or GPIO2, have multiple functions and some of them are shared among onboard and external peripheral devices. Certain combinations of peripherals cannot work together. For example, it is not possible to do JTAG debugging of an application that is using SD card, because several pins are shared by JTAG and the SD card slot.

In other cases, peripherals can coexist under certain conditions. This is applicable to, for example, LCD screen and SD card that share only a single pin GPIO21. This pin is used to provide D/C (Data/Control) signal for the LCD as well as the Card Detect signal read from the SD card slot. If the card detect functionality is not essential, then it may be disabled by removing R167, so both LCD and SD may operate together. For more details on which pins are shared among which peripherals, please refer to the table in the next section. Main I/O Connector/JP1 The JP1 connector consists of 14x2 male pins whose functions are shown in the middle two "I/O" columns of the table below. The two "Shared With" columns on both sides describe where else on the board a certain GPIO is used. .. list-table:: :widths: 30 20 20 30 :header-rows: 1 - I/O - I/O - Shared With - 3.3V - GND - n/a - IO32 - IO33 - NC/XTAL - IO12 - IO13 - JTAG，microSD - IO14 - IO27 - Camera - IO26 - IO25 - Camera, LCD - IO35 - IO34 - Camera - IO39 - IO36 - Camera - EN - IO23 - Camera, LCD - IO22 - IO21 - Camera, LCD, microSD - IO19 - IO18 - Camera, LCD - IO5 - IO17 - PSRAM - IO16 - IO4 - LED, Camera, microSD - IO0 - IO2 - LED, microSD - IO15 - 5V - Legend: .
