Shadow Shadow requested changes for Split Keyboard ago

Hey! Very cool work on the split keyboard but, please read the submission guidelines and have all the required files in your repo! You would need a top case for the keyboard. Also the diodes you are buying doesn't match the footprint used, please make sure they are correct! and as of now this isn't a tier 2 project , could you please change to tier 3 and optimize your BOM under that

Case Design

  • CASE: Finished making the 4x5 + 2 case for both left and right modules.
  • It is just a simple base to hold the pcb and has enough space to place batteries.
