risc-v espressif can run rust now I think?

Rust can be compiled to most Espressif MCUs. The critical difference is if there is standard library support. ESP8266 is an older design but can still be a Rust no_std target [0]. Espressif did release a board [1] for use with Rust training designed for the board [2].

Hey thanks for the links, you seem very knowledgable ;) I am actively looking for any good information or even good hacker communities using ESP32 for some hobby embedded things. Care to recommend any? Thanks again!

I’m just a beginner myself, learning slowly. There is so much out there that a recommendation would need more information about your goals. Something that I recommend elsewhere in this topic is Dronebot Workshop. That person has well done videos with an excellent companion website. One of the tricks is understanding what information is too old to be helpful.

A very accessible starter project that I would suggest is to use an Wemos Mini esp8266 and an 8x8 led panel. Desolder leads from the panel and solder the 5v, ground and d4 pin from the Wemos to it. Attach to computer via usb and open the WLED website below to load the firmware on the ESP. Then open the on-ESP website or use the WLED app to go wild with colors.

Wemos mini: https://www.amazon.com/Organizer-ESP8266-Internet-Developmen...

Nearly any Wemos Mini D1 clone will work.
