Description

This four-key membrane switch keypad with a 1x4 grid is simple to operate and complements your project well. It has 5 outputs and 4 keys, using the "Scan Mode" to determine which button is pressed. It supports platforms like Arduino, AVR, PIC, STM, and Raspberry Pi. This low-profile keypad can be placed almost anywhere. The four keys are connected in a 1x4 matrix that an Arduino can easily interpret. The electrical connection is made via a flat flexible ribbon cable with a breadboard-compatible 0.1" pitch single-row female connector.
