This PCB was designed to act as two accent pixels. If you are using a board that supports accent pixels (DIYino, Proffie, Teensy, etc) you can use it to control the pixels. The only other option would be to wire it to the blade, but then they would just match the blade.
It would be possible to make a version that just included regular LEDs that would be controlled the accent pads of a less programmable board, but I am not sure if it's worth making unless you are interested in having a batch made.
