Demo video of the console in action The CH32V003 is an interesting little chip - not just because it’s based on the up-and-coming RISC-V architecture, or because it comes in a tiny package, but mostly because you can buy it for $0.09 in bulk. Hard to believe this is a 32-bit microcontroller... albeit one with only 2KiB of RAM and 16KiB of flash. It puts the CH32V003 in the same ballpark as the classic Atmel ATmega328P - the heart of the original Arduino - but with significantly more grunt: 48MHz...
