4x4 Matrix Membrane Keypad Module

Add a sleek, low-profile user input interface to your electronics with the premium 4x4 Keypad Matrix Membrane Switch Module. Explicitly engineered to maximize input options while conserving microcontroller pins, this ultra-thin matrix array routes 16 independent keys into an efficient 8-pin layout (4 rows and 4 columns). Constructed from high-durability, self-adhesive flexible membrane material, it features a tactile dome switch design underneath each overlay tile to assure reliable, bounce-free key presses over a massive operating lifetime. Outfitted with an integrated, flexible ribbon cable terminating in a standard 2.54mm pitch female header, it serves as the definitive, plug-and-play component choice for building smart digital door locks, secure ATM pin entry panels, conveyor control nodes, custom musical synthesizers, and electronic calculator prototypes driven by Arduino, ESP32, or Raspberry Pi.
