Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Specifically the CH32V303RCT6? I'd love to design some hardware for it.

Too short of RAM and Flash to do anything very interesting. MM2 firmware with MM+ I/O is about all you could achieve. No advantage at all over something like the cheap STM32F407 with the ArmmiteF4 firmware

Which is tried, tested, supported (bug fixes etc) & works really well :)

The CH32V303RCT6 is under 1 USD on Aliexpress. The STM32F407 is about 11 USD on Digikey. In any case, thanks for replying.

STM32F407 £1.4 on Aliexpress if you compare like with like supply for a much more powerful chip (RAM, FLASH, clock)
