This is AEBoard's first EC PCB, available to drop into AEBoard's Satellite Keyboard. This EC Update kit will include everything you need to convert your existing Satellite keyboard from MX to EC.
See Lightning's comprehensive build guide on his website.
No soldering is required, only a screwdriver. Included are 2 bags of screws (one set for PCB, one set for plate) and 1 bag of brass standoffs.
