NodeMCU ESP32
|
|
=============
|
|
|
|
The NodeMCU ESP32 board (in some cases also known as ESP32-DevkitC)
|
|
is fully supported by esphomeyaml. Simply select ``ESP32`` when
|
|
the esphomeyaml wizard asks you for your platform and |nodemcu-32s|_ as the board type.
|
|
|
|
.. |nodemcu-32s| replace:: ``nodemcu-32s``
|
|
.. _nodemcu-32s: http://docs.platformio.org/en/latest/platforms/espressif32.html#nodemcu
|
|
|
|
.. code:: yaml
|
|
|
|
# Example configuration entry
|
|
esphomeyaml:
|
|
name: livingroom
|
|
platform: ESP32
|
|
board: nodemcu-32s
|
|
|
|
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!

Pins on the NodeMCU ESP32 development board.
|
|
|
|
Note that in certain conditions you *can* use the pins marked as ``INTERNAL`` in above image.
|
|
|
|
- ``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:`/esphomeyaml/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 </esphomeyaml/components/binary_sensor/esp32_touch>` like some other
|
|
pins.
|
|
- ``5V`` is connected to the 5V rail from the USB bus and can be used to power the board. Note that
|
|
the UART chip is directly connected to this rail and you therefore **cannot** supply other voltages
|
|
into this pin.
