4x4 keyboard keypad module
A 4×4 matrix membrane keypad with 16 tactile buttons, ideal for adding user input to microcontroller projects. The keypad uses a standard 8-pin matrix wiring scheme (4 rows × 4 columns), requiring only 8 GPIO pins to read all 16 keys.
The flexible membrane design is thin and lightweight, making it easy to mount on enclosures or panels. Compatible with Arduino, Raspberry Pi, and other microcontrollers using common keypad scanning libraries.
