Membrane 4×4 Matrix Keypad



This matrix keypad has 16 buttons arranged in a 4 x 4 pattern. The number pad is similar to that found on a telephone (with the addition of letters in the 4th column). Since the keypad uses a matrix arrangement, only 8 digital inputs are require to add this to your project.

The connector uses a standard breadboard pitch (0.100” / 2.54mm) and can be used with the standard Arduino Matrix Keypad Library found in the Arduino IDE.


  • Standard breadboard pitch (0.100” / 2.54mm)
  • Only requires 8 digital inputs
  • Adhesive backing
  • Works with built in Arduino library
