The manufacturer’s similar chips max out at 64K - still it would make a more beginner-friendly project: Color makes a big difference in impact!

  >The manufacturer’s similar chips max out at 64K Perhaps these should be considered. 64KB is a world better than the 2K in the selected variant (CH32V003) in that micro-controller family.

    As pointed out in my other comment, you can add vast amounts of extra functionality for very little cost, up to a Linux-running board with 64 MB RAM for $5. But that's not the point. The point is: what is the cheapest stand-alone usable computer you can make? "Usable" in the same sense as a ZX80 or Altair 8800 or Apple I of course, not in the sense of a modern computer. If you pay 50c for the CPU instead of 10c then you just increased the total cost by 50%.

      >If you pay 50c for the CPU instead of 10c then you just increased the total cost by 50%. True. But is the difference actually 5x? CH32V003 shouldn't be the only option.
