In the last post, I was working on a PCB design for a 40% (48 key) mechanical keyboard. I touched up the circuitry, and Shirley capped it off with an amazing illustration.

Here is the render of our design: cATTACK!

The overall specs:

  • 48 Keys in an Ortholinear (grid) format
  • Bluetooth LE via the Adafruit Bluefruit 32u4 Feather microcontroller
  • Hotswapping MX compatible switches via Kaihl Sockets
  • Silkscreen illustration by Shirley

The next step is to get this prototype manufactured and assembled, then write the firmware….
