Status af my #Teensy2 powered #dactyl keyboard: breadboarding is ongoing, I have a functional 4-button keyboard (aoeu on Dvorak, asdf on qwerty).

The I²C connection to the MCP23018 IO expander works, but not yet fully through the TRRS jack cable (I think it's bad connection/soldering on one of the pins, that's on me). Six months ago I wouldn't have known what any part of than previous sentence meant 😅 it's a wonderful learning journey.
