Other key parts include the Longan_Nano. By type, the board carries 48 LEDs, 41 diodes, 4 resistors, 2 capacitors, 1 IC and 1 switch.

It belongs with the keyboards designs in this gallery.

From the project

KUSOboard is a Longan Nano based keyboard using KarlK90's branch of QMK

Regarding the naming of the files, I had started out meaning to make an Atreus size board, but decided against it shortly after starting the project. It was reduced to something more like a Reviung39.
