Description
Jornada keyboard USB interface
The assumption was to build a Jornada-like palmtop around Jornadas leftover keyboard. Since this keyboard has no own interface board that could be used to connect to Raspbeery Pi, Radxa Zero or similar SBC I had to build a PCB that allows it.
A solution for use Jornada's keyboard was initially created for the project described here https://www.thingiverse.com/thing:6938611
This finally ended up with this project https://www.thingiverse.com/thing:6966529
