This is a quick project that Ari and I built. Link to repo:
We built it with the Keyboard Club Event as the deadline.
We went through several iterations, in software and hardware.
Here was the first PCB: It had a scuffed USB-C arrangement, also we switched to use a epaper display.
The second PCB was better, still a bit off though: Main issues were:
TP2 and TP3 were reversed (spliced the cable) Bad solder joints on headphone jack (resoldered) Lights were 180 degrees off (resoldered) Ruined epaper display with wrong code Case needed to be adjusted to fit headphone jack (redesigned and printed 2x) Nevertheless, we are stoked to see how it turned out for the event!...
