I bought two Sol 2 keyboards: one polycarbonate with a 4mm aluminum plate, the other with a bent steel case and carbon fiber plate. However, I am was too fond of the bent steel version and decided to sell it unbuilt.
Initially, I assembled this board with hotswap OLED displays and used Mill-Max sockets to make the board hotswap. However, since I did not solder the sockets, some switches has issues registering.
This board is still unbuilt, but the plan is to solder two rotary encoders, fix the OLEDs, and solder Zealious 67g switches.
