This 16-button keypad provides a useful human interface component for microcontroller projects. It's made of a thin, flexible membrane material with an adhesive backing 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. Check the tutorials tab for links to an Arduino library and example code.

We include an 8-pin extra-long header strip so you can plug this into a breadboard with ease.

Features:

  • Ultra-thin design & adhesive backing provides easy integration to any project
  • Easy communication with any microcontroller
  • Maximum Rating: 24 VDC, 30 mA
  • Interface: 8-pin access to 4x4 matrix
