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
