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!
