The ESP-IDF changes quickly and MicroPython only supports certain versions. The
current recommended version of ESP-IDF for MicroPython is v5.5.1. MicroPython
also supports v5.2, v5.2.2, v5.3, v5.4, v5.4.1 and v5.4.2.
also supports v5.3, v5.4, v5.4.1 and v5.4.2.
To install the ESP-IDF the full instructions can be found at the
[Espressif Getting Started guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html#installation-step-by-step).
