The Bug54 is a 54-key split by Oliver Gründel aka ogruendel/Cozy_04. Wireless via nice!nano, featuring a 4x6 column staggered layout with 3 thumb keys.

After wanting to get a split keyboard I decided I would build my own just to have a nice project to do. This is what it turned out as. […] super low profile for portablility (< 6mm case and < 14mm overall) – Oliver.

Specs

• 54 keys (6x4 + 3)
• low-pro Choc V1 switches, hotswap
• reversible PCB
• nice!nano V2
• 3D-printed frame (optional)
• ZMK support
