# Hardware Infos It's planed to make a nice version of the hacking hardware including PCB design and a BOM - someone in the future ;-) Currently I provide the current status of the designed hardware used in the HW Hacking 101 sessions. The used keypad is a standard 4x4 matrix keypad you'll found for arduino and co.
