Buildguide

Step-by-step

Solder hotswap sockets in markings
Solder capacitors C1, C2 in markings
LSB 4 only - If you are mounting the OLED, solder Resistors R1, R2 & OLED Screen in place
Solder Encoder
Solder controller, face up, flush with underside of PCB (*)
Assemble plate/spacers around the PCB (**)
Insert switches/caps (remember to support the sockets!) and add encoder wheel
Program
Enjoy!

(*) The controller can be socketed, but that adds height, and you need longer spacers than the ones included if purchasing a kit.

(**) For LSB 4, the unused plate forms the bottom, unless a solid backplate is added as an optional extra. Breakaway tabs need to be removed and filed before use.
