Software
The Sipeed AI & IoT board supports original standalone SDK, FreeRTOS SDK based on C/C++.
You can port micropython on it: http://en.maixpy.sipeed.com/.
It also supports FPIOA, GPIO, TIMER, PWM, Flash, OV2640, LCD. And it has zmodem, vi, SPIFFS on it, so that you can edit python directly or sz/rz file to board.
Seedstudio offers even more support to your project with their GitHub contributions:
