Description:

The 44 Matrix Membrane Keypad is a compact and reliable input device designed for a wide range of electronics, embedded systems, and microcontroller-based projects. Featuring 16 tactile keys arranged in a 4-row by 4-column matrix, this keypad allows users to easily enter numbers, commands, passwords, and control inputs while minimizing the number of I/O pins required.

Built using a durable membrane structure with high-quality conductive contacts, the keypad offers excellent responsiveness, long operational life, and low power consumption. Its thin and lightweight design includes a self-adhesive backing, making it easy to mount on project enclosures, control panels, and prototypes.

The keypad connects through an 8-pin ribbon cable and is fully compatible with popular development platforms such as Arduino, ESP32, Raspberry Pi, STM32, PIC, and AVR microcontrollers. It is widely used in access control systems, security locks, robotics, automation equipment, calculators, menu-driven interfaces, and educational STEM projects.
