## Overview {#esp32s2_devkit_overview}
|
||||
|
||||
The Espressif ESP32-S2-DevKit boards are a couple of boards that use one of
|
||||
the following modules:
|
||||
|
||||
- ESP32-S2-MINI-1x-N4 module (ESP32-S2-DevKitM-1 board)
|
||||
- ESP32-S2-MINI-1x-N4R2 module (ESP32-S2-DevKitM-1R board)
|
||||
- ESP32-S2-SOLO-N4 module (ESP32-S2-DevKitC-1 board)
|
||||
- ESP32-S2-SOLO-N4R2 module (ESP32-S2-DevKitC-1R board)
|
||||
- ESP32-S2-WROOM module (ESP32-S2-Saola-1 board)
|
||||
- ESP32-S2-WROVER-N4R2 module (ESP32-S2-Saola-1R board)
|
||||

||||
\image html "https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/_images/esp32-s2-devkitm-1-v1-annotated-photo.png" "Espressif ESP32-S2-DevKitM-1" width=600px
|
||||
|
||||
<br>
|
||||
Due to the different modules used, the available versions of the
|
||||
ESP32-S2-DevKit board differ regarding the Flash size, the integrated SPI RAM
|
||||
and the SPI voltage. To be able to use all these different versions of the
|
||||
board with a single board definition, used board version can be specified
|
||||
by the variable `BOARD_VERSION` during compilation, for example:
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
BOARD=esp32s2-devkit BOARD_VERSION=esp32s2-devkitc-1r make ...
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The following table shows the available board versions, the size of the
|
||||
Flash and the SPI RAM as well as the value of the variable `BOARD_VERSION`
|
||||
that is used to specify the board version.
|
||||
|
||||

@note
|
||||
- If the board version is not specified, <b>ESP32-S2-DevKitM-1 with 4 MByte
|
||||
Flash</b> is assumed and `BOARD_VERSION` is set to <b>`esp32s2-devkitm-1`</b>
|
||||
by default.
|
||||
- Using a board version with embedded SPI RAM (`BOARD_VERSION` is any of
|
||||
<b>`esp32s2-*-1r*`</b> values) enables the
|
||||
\ref esp32_spi_ram "esp_spi_ram" feature. The SPI RAM can then be used as
|
||||
heap by enabling the \ref esp32_spi_ram "esp_spi_ram" pseudomodule.

## Hardware {#esp32s2_devkit_hardware}
|
||||
|
||||
This section describes
|
||||
|
||||
- the [MCU](#esp32s2_devkit_mcu),
|
||||
- the default [board configuration](#esp32s2_devkit_board_configuration),
|
||||
- [optional hardware configurations](#esp32s2_devkit_optional_hardware),
|
||||
- the [board pinout](#esp32s2_devkit_pinout).

|
||||
### MCU {#esp32s2_devkit_mcu}
|
||||
|
||||
Most features of the board are provided by the ESP32-S2 SoC. For detailed
|
||||
information about the ESP32-S2 SoC variant (family) and ESP32x SoCs,
|
||||
see section \ref esp32_mcu_esp32 "ESP32 SoC Series".
|
||||
|
||||
[Back to table of contents](#esp32s2_devkit_toc)
|
||||
|
||||
### Board Configuration {#esp32s2_devkit_board_configuration}
|
||||
|
||||
ESP32-S2-DevKit boards have no special hardware on board with the exception
|
||||
of a single pin RGB-LED that uses a special bit-oriented protocol to
|
||||
control the RGB-LED by 24-bit RGB values which is not supported yet.
|
||||
|
||||
All GPIOs are simply broken out for flexibility. Therefore, the board
|
||||
configuration is the most flexible one which provides:
|
||||
|
||||
- 20 x ADC channels at maximum
|
||||
- 2 x SPI
|
||||
- 1 x I2C
|
||||
- 2 x UART
|
||||
- 1 RGB-LED
|
||||
|
||||
Since almost GPIOs have broken out, GPIOs can be used for different purposes
|
||||
in different applications. Following GPIOs are used for Flash and SPI RAM and
|
||||
are not broken out:
|
||||
|
||||
- ESP32-S2-DevKitC-1x: GPIO27..GPIO32
|
||||
- ESP32-S2-DevKitM-1x: GPIO26..GPIO32
|
||||
- ESP32-S2-Saola-1x: GPIO26..GPIO32
|
||||
|
||||
For flexibility, GPIOs can be used in multiple peripheral configurations,
|
||||
but they can only be used for one peripheral at a time. For example, GPIO9
|
||||
is used in the ADC channel definition and the definition of the SCL signal
|
||||
for I2C_DEV(0).
|
||||
|
||||
This is possible because GPIOs are only used for a specific peripheral
|
||||
interface when either
|
||||
|
||||
- the corresponding peripheral module is used, e.g. `periph_i2c`, or
|
||||
- the corresponding init function is called, e.g. `adc_init`.
|
||||
|
||||
That is, the purpose for which a GPIO is used depends on which module
|
||||
or function is used first.
|
||||
|
||||
For example, if module `periph_i2c` is not used, the GPIOs listed in I2C
|
||||
configuration can be used for the other purposes, that is, GPIO9 can be
|
||||
used as ADC channel.
|
||||
|
||||
The following table shows the default board configuration, which is sorted
|
||||
according to the defined functionality of GPIOs. This configuration can be
|
||||
overridden by \ref esp32_application_specific_configurations
|
||||
"application-specific configurations".

## Flashing the Device {#esp32s2_devkit_flashing}
|
||||
|
||||
Flashing RIOT is quite easy. The board has a Micro-USB connector with
|
||||
reset/boot/flash logic. Just connect the board to your host computer
|
||||
