Description

4 x 4 Matrix Keypad Membrane Switch Keypad has 16 buttons, arranged in a telephone-line 4×4 grid. It’s made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 8 microcontroller pins (4-columns and 4-rows) to scan through the pad.
