Product description: Buttonmatrix - 4x4 keyboard matrix - Joy-IT
The Buttonmatrix 4x4 module is a practical input solution designed for use with microcontrollers and single-board computers. The module features 16 tact-switch buttons arranged in a 4x4 matrix, allowing for efficient operation of multiple keys while utilizing a small number of GPIO lines. By scanning rows and columns, the module enables reliable reading of all button states using only eight microcontroller pins . This solution is ideal for projects requiring control panels, numeric keypads, access control systems, or user interfaces.
