Choking Hazard

Tiny 8 switch keypad

  • Piggybacks onto a Pro Micro
  • Tiny 18 x 35mm
  • 6mm x 6mm tactile switches
  • Simple Arduino sketch

Socketed Pro Micro. Leads cut from diodes soldered in place.

 Pins from switches cut flush to PCB. Kapton tape to insulate the pins from the USB connector.

Assembled. Another soldered permanently together using pin headers.

Tight fit.

3M Command strips, removable double sided foam tape.

Stuck on one of my machines. Yes, I know it is blocking the drive door.
