Electronic control system for an electro-pneumatic drill


Boards for the control of electro-pneumatic drills

Control board for an electro-pneumatic drill, developed in two versions: BASIC and PRO.

Both versions feature a 1.5-inch 128x128 pixel white #OLED display for parameter visualization, including battery status, speed, hole count, sensor status, and more. The boards are connected via flat cables and quick-connect connectors.
