Other key parts include the nice_nano. By type, the board carries 82 switches, 80 diodes, 1 IC and 1 connector.

It belongs with the keyboards and iot & wireless designs in this gallery.

From the project

80 key wireless custom keyboard with ZMK.

The ByranTK-Alpha is an 80 key custom mechanical keyboard, designed to be made with any material. "All the keys you need and no more."

1. Order all the parts - I ordered everything off of JLCPCB, with SMT assembly for the diodes because I'm lazy. The pick and place/bom files are in the bom folder, ready for upload to JLCPCB. It is highly suggested you use SMT assembly because it is extremely cheap and saves a lot of time. - Apparantly, you can also get smt hotswap sockets assembled too, though I did not do that. 2. Solder it all together - Solder on the hotswap sockets and the nice!nano.…
