docs

As discussed in the forum post ESP-32 WROOM discrepancy in quickref page, the ESP32 quickref documentation should be improved in the guidance given for pin usage.

In particular, some of the different models have different pin restrictions. Need to at least consider the WROOM, WROVER and PICO D4.

hiya for the esp32 pico v3 chip variant of the esp32, pin 20 is exposed:

but in the esp32 board definition this pin isnt available because WROVER and WROOM modules don't have this pin available
https://github.com/micropython/micropython/blob/master/ports/esp32/machine_pin.c#L96
shall i submit a PR to change this so the pin is valid?

Assessment

Q Qwen · high

Issue #7068 is a documentation request to improve ESP32 quickref guidance regarding pin restrictions across different models (WROOM, WROVER, PICO D4). Issue #8393 is a technical bug/feature request about a specific pin (pin 20) being missing from the ESP32 Pico v3 board definition in the code. While both issues concern ESP32 pin availability and mention the same module types (WROOM/WROVER), they address different aspects: one is documentation improvement, the other is code implementation. The candidate does not resolve the documentation request in #7068.

Suggested action

Keep both issues open. #7068 should be addressed by updating the quickref documentation. #8393 should be addressed by updating the board definition code if the pin is indeed available on the Pico v3 variant.
