Generic Matrix Keyboard Print

Last Updated or created 2023-06-20

I only have to check my new design for a generic matrix keyboard once again, and then i’m going to order a few of these prints.

  • 32 keys (2 blocks of 16)
  • 1 key is changeable from generic key to reset signal key
  • jumper header connector VCC, GND, DataAvailable, Reset and 5 data lines

I’ve used the opensource tool freeroute to autoroute the coppertraces

  • From Kicad export PCB in Spectra DNS format
  • Open Freeroute and run autoroute
  • export as Spectra Session File
  • In kicad import this session file again

Autotraced …
Current setup
