All ESP32-based devices are supported by ESPHome. Simply select ``ESP32`` when
|
|
the ESPHome wizard asks you for your platform and choose a board type
|
|
from `this link <http://docs.platformio.org/en/latest/platforms/espressif32.html>`__ when the wizard
|
|
asks you for the board type.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
esphome:
|
|
name: livingroom
|
|
platform: ESP32
|
|
board: <BOARD_TYPE>
|
|
|
|
The ESP32 boards often use the internal GPIO pin numbering on the board, this means that
|
|
you don't have to worry about other kinds of pin numberings, yay!
|
|
|
|
Some notes about the pins on the ESP32:
|
|
|
|
- ``GPIO0`` is used to determine the boot mode on startup. It should therefore not be pulled LOW
|
|
on startup to avoid booting into flash mode. You can, however, still use this as an output pin.
|
|
- ``GPIO34``-``GPIO39`` can not be used as outputs (even though GPIO stands for "general purpose input
|
|
**output**"...)
|
|
- ``GPIO32``-``GPIO39``: These pins can be used with the :doc:`/components/sensor/adc` to measure
|
|
voltages.
|
|
- ``GPIO2``: This pin is connected to the blue LED on the board as seen in above picture. It also supports
|
|
the :doc:`touch pad binary sensor </components/binary_sensor/esp32_touch>` like some other
|
|
pins.
