Support for Olimex ESP32-POE Board #7337

Open ab-tools opened 1 year ago

ab-tools commented 1 year ago

As the Olimex ESP32-POE board is currently not listed on the CircuitPython downloads page I assume this is not supported so far: https://www.olimex.com/Products/IoT/ESP32/ESP32-POE-ISO/

That is a great board, however, and one of the very few (if not the only) option if you need a very compact and energy efficient board with PoE support.

Is there a chance CircuitPython could add support for this?

This would be highly appreciated, thanks for all the efforts with this great project. Andreas

We generally rely on board users or manufacturers to add third-party boards. If you'd like to try it yourself, see: https://learn.adafruit.com/how-to-add-a-new-board-to-circuitpython https://learn.adafruit.com/how-to-add-a-new-board-to-the-circuitpython-org-website

Hello Dan,

first thanks a lot for your reply quick reply which is much appreciated!

I would be happy to help with that and I do think that I could get it to work in WiFi mode as this board is based on the regular ESP32 chip - so copying the configuration from one of the already supported boards should work. Here the hardware configuration of that board from PlatformIO which supports it: https://docs.platformio.org/en/latest/boards/espressif32/esp32-poe-iso.html

The main challenge I see is adding support for the LAN8720 chip which is obviously a bit the point of this board (so using LAN instead of WiFi when PoE is used for power supply anyway).

As I understand MycroPython added support for it by this commit: https://github.com/petrkr/micropython/commit/bf1cf5eed874a4debf47fda9ef5fb482251f4df8

I would be happy to prepare a fork with new branch for this board based on an already supported Espressif 32 ESP32 board and obviously I could also do all the testing. But surely I would need some support from a more experienced CircuitPython developer to help adding support for this LAN chip.

Would you be able to support with this?

Thanks again Andreas

I don't think supporting any LAN chips is a priority for Adafruit-funded folks in the near-term. We'd be happy to review and merge support though.
