This component contains platform-specific options for the ESP32 platform.

# Example configuration entry

|
esp32:
|
|
board: nodemcu-32s
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **board** (**Required**, string): The PlatformIO board ID that should
|
|
be used. Choose the appropriate board from
|
|
`this list <https://registry.platformio.org/packages/platforms/platformio/espressif32/boards>`__ (the icon next to the name
|
|
can be used to copy the board ID). *This only affects pin aliases, flash size and some internal settings*, if unsure
|
|
choose a generic board from Espressif such as ``esp32dev``.
|
|
- **framework** (*Optional*): Options for the underlying framework used by ESPHome.
|
|
See :ref:`esp32-arduino_framework` and :ref:`esp32-espidf_framework`.
|
|
- **variant** (*Optional*, boolean): The variant of the ESP32 that is used on this board. One of ``esp32``,
|
|
``esp32s2``, ``esp32s3``, ``esp32c3`` and ``esp32h2``. Defaults to the variant that is detected from the board, if
|
|
a board that's unknown to ESPHome is used, this option is mandatory.
|
|
|
|
.. _esp32-arduino_framework:
|
|
|
|
Arduino framework
|
|
-----------------
|
|
|
|
This is the default framework for ESP32 chips at the moment.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
esp32:
|
|
board: nodemcu-32s
|
|
framework:
|
|
type: arduino
|
|
version: 2.0.0
|
|
|
|
- **version** (*Optional*, string): The base framework version number to use, from
|
|
`ESP32 arduino releases <https://github.com/espressif/arduino-esp32/releases>`__. Defaults to ``recommended``. Additional values are:
|
|
|
|
- ``dev``: Use the latest commit from https://github.com/espressif/arduino-esp32, note this may break at any time
|
|
- ``latest``: Use the latest *release* from https://github.com/espressif/arduino-esp32/releases, even if it hasn't been recommended yet.
|
|
- ``recommended``: Use the recommended framework version.
|
|
|
|
- **source** (*Optional*, string): The PlatformIO package or repository to use for framework. This can be used to use a custom or patched version of the framework.
|
|
- **platform_version** (*Optional*, string): The version of the `platformio/espressif32 <https://github.com/platformio/platform-espressif32/releases/>`__ package to use.
|
|
|
|
.. _esp32-espidf_framework:
|
|
|
|
ESP-IDF framework
|
|
-----------------
|
|
|
|
This is an alternative base framework for ESP32 chips, and recommended for variants
|
|
of the ESP32 like ESP32S2, ESP32S3, ESP32C3 and single-core ESP32 chips.
|
|
|

# Example configuration entry
|
|
esp32:
|
|
board: esp32-c3-devkitm-1
|
|

|
|
type: esp-idf
|
|
version: recommended
|
|
# Custom sdkconfig options

CONFIG_COMPILER_OPTIMIZATION_SIZE: y
|
|
# Advanced tweaking options
|
|
advanced:
|
|
ignore_efuse_mac_crc: false
|
|
|
|
- **version** (*Optional*, string): The base framework version number to use, from
|
|
`ESP32 ESP-IDF releases <https://github.com/espressif/esp-idf/releases>`__. Defaults to ``recommended``. Additional values are:
|
|
|
|
- ``dev``: Use the latest commit from https://github.com/espressif/esp-idf, note this may break at any time
|
|
- ``latest``: Use the latest *release* from https://github.com/espressif/esp-idf/releases, even if it hasn't been recommended yet.
|
|
- ``recommended``: Use the recommended framework version.
|
|
|
|
- **source** (*Optional*, string): The PlatformIO package or repository to use for the framework. This can be used to use a custom or patched version of the framework.
|
|
- **platform_version** (*Optional*, string): The version of the `platformio/espressif32 <https://github.com/platformio/platform-espressif32/releases/>`__ package to use.
|
|
- **sdkconfig_options** (*Optional*, mapping): Custom sdkconfig options to set in the ESP-IDF project.
|
|
- **advanced** (*Optional*, mapping): Advanced options for highly specific tweaks.
|
|
|
|
- **ignore_efuse_mac_crc** (*Optional*, boolean): Can be set to ``true`` for devices on which the burnt in MAC address does not
|
|
match the also burnt in CRC for that MAC address, resulting in an error like ``Base MAC address from BLK0 of EFUSE CRC error``.
