4x4 Matrix Keypad

About this product

Compact 16-button matrix keypad featuring a flat membrane design with a self-adhesive backing. Uses a simple row-and-column layout to scan digits 0-9, letters A-D, and symbols * and #. Interfaces with microcontrollers via an 8-pin female header (2.54mm pitch) on a flexible ribbon cable, saving I/O pins.

Ultrasonic, IR, temperature, humidity, motion, current, camera and RF sensor modules - plus relay, logic-level and breakout boards for prototyping and production.
