From the project

A collection of PCBs aimed at supporting handwired dactyl-ish keyboards.

A collection of PCBs aimed at supporting handwired dactyl-ish keyboards. The goal is faster, simpler assembly (by offloading the key matrix from the handwiring to the PCB) and flexibility in placement of keys and connectors.

The intent is to connect keyswitches to the PCB using hotswap sockets, soldered to ribbon cables with DuPont connectors on the other side, which can plug in to the header on the long side of the PCB.
