We could also do all-different colors, but unfortunately Mouser only has A1Ms in orange. Expensive, about $3 each. *** Replacing LEDs in these is supposed to be more stable than MK's, but it's unclear whether JLCPCB is still the best option. This page is to tumblr, but there's a url in the top if you received the program under these conditions, and telling the user how to switch modes. PRs welcome.
