## Overview {#esp32h2_devkit_overview}
|
||||
|
||||
The Espressif ESP32-H2-DevKitM-1 board uses the ESP32-H2-MINI-1x module.
|
||||
|
||||
Since the number of GPIOs and their possible uses on the ESP32-H2 are quite
|
||||
limited, the ESP32-H2-DevKitM-1 should also work for most other ESP32-H2 boards.
|
||||
Any modifications required for specific applications could be overridden by
|
||||
\ref esp32_application_specific_configurations "application-specific board configuration".

||||

## Hardware {#esp32h2_devkit_hardware}
|
||||
|
||||
This section describes
|
||||
|
||||
- the [MCU](#esp32h2_devkit_mcu),
|
||||
- the default [board configuration](#esp32h2_devkit_board_configuration),
|
||||
- [optional hardware configurations](#esp32h2_devkit_optional_hardware),
|
||||
- the [board pinout](#esp32h2_devkit_pinout).
|
||||

||||

|
||||
|
||||
### MCU {#esp32h2_devkit_mcu}
|
||||
|
||||
Most features of the board are provided by the ESP32-H2 SoC. For detailed
|
||||
information about the ESP32-H2 variant (family) and ESP32x SoCs,
|
||||
see section \ref esp32_mcu_esp32 "ESP32 SoC Series".
|
||||
|
||||
[Back to table of contents](#esp32h2_devkit_toc)
|
||||
|
||||
### Board Configuration {#esp32h2_devkit_board_configuration}
|
||||
|
||||
ESP32-H2-DevKitM-1 boards have no special hardware on board with the exception
|
||||
of a WS2812-compatible RGB-LED.
|
||||
|
||||
All GPIOs are simply broken out for flexibility. Therefore, the board
|
||||
configuration is the most flexible one which provides:
|
||||
|
||||
- 5 x ADC channels at maximum
|
||||
- 1 x SPI
|
||||
- 1 x I2C
|
||||
- 1 x UART
|
||||
- 2 x PWM with 3 channels each
|
||||
- 1 x RGB-LED
|
||||
|
||||
Since all GPIOs are broken out, GPIOs can be used for different purposes
|
||||
in different applications. For flexibility, GPIOs can be listed in multiple
|
||||
peripheral configurations, but they can only be used for one peripheral
|
||||
at a time. For example, GPIO1, GPIO3, GPIO4 and GPIO5 can be used as ADC
|
||||
channels or as signals for SPI_DEV(0) and PWM_DEV(1).
|
||||
|
||||
This is possible because GPIOs are only used for a specific peripheral
|
||||
interface when either
|
||||
|
||||
- the corresponding peripheral module is used, i.e. `periph_spi`, or
|
||||
- the corresponding init function is called, i.e. `adc_init`, or
|
||||
- the corresponding init function is called, i.e. `pwm_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_spi` is not used, the GPIOs listed in SPI
|
||||
configuration can be used for the other purposes, that is, GPIO1, GPIO4 and
|
||||
GPIO5 can be used as ADC channels or PWM channels.
|
||||
|
||||
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".

@note
|

- The configuration of ADC channels contains all ESP32-H2 GPIOs that could
|
||||
be used as ADC channels.
|
||||
- GPIO6 and GPIO7 are not broken out for any reason.
|
||||
- GPPIO15 to GPIO21 are used for the in-package flash and are not broken out.
|
||||

|

boards, see section \ref esp32_peripherals "Common Peripherals".

## Flashing the Device {#esp32h2_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
|
||||
and type using the programming port:
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
make flash BOARD=esp32h2-devkit ...
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
For detailed information about ESP32-H2 as well as configuring and compiling
|
||||
RIOT for ESP32-H2 boards, see \ref esp32_riot.
