N.B: Although this board works fine, its a bit difficult to use, since it will slide around, due to only 2 edges touching the table.
To build it you need to order pcbs, check out the releases.
You will also need the following parts: 2 x Blackpill MCU 2 x TRRS Jack 36 x MX switches and keycaps 4 x 2.54mm Double Row Right angle Male Breakaway PCB Board Pin Header Connector(2x5 pins) 1 x USB C cable 1 x TRRS cable (only need 3 poles)
