This is a Left Hand Mini 1800 style keyboard that was my first project to learn PCB design through KiCAD. The PCB design is based around a ProMicro and daughter board which uses USB mini-B similar to the Tanuki Keyboard. The PCB only supports the layout that is shown in the image above. Please feel free to modify the PCB or case files to fit your needs.
The case is a typical top mounted desin with the intention for it to be 3D printed with the mounting solution being M2 heat-set inserts and screws. I sourced my hardware from McMaster-Carr:
M2 Heat-Set Insert qty 10
M2 Screws qty 10
