This Arduino 4×3 Matrix 12 keys Membrane Switch Keypad 4×3 Matrix is high-quality soft touch feeling button with 100 million life-stroke lifespans and good resistance to environmental conditions. This 12-button Keypad 4×3 Matrix provides a useful human interface component for microcontroller projects. Convenient adhesive backing provides a simple way to mount the keypad in a variety of applications.

This is a membrane keypad with no moving parts. A female 7-pin berg connector is require for interfacing it with your microcontroller circuits.

This is a simple and widely used input device for various electronic projects and embedded systems. It consists of 12 buttons arranged in a grid of 4 rows and 3 columns. Typically labeled with numbers (0-9) and additional symbols like the asterisk (*) and hash (#). Each button press generates a unique signal based on its row and column combination. Which can be easily detected and processed by a microcontroller.

Its matrix configuration allows efficient wiring, as each button does not require a separate input pin

The matrix keypad is easy to integrate with popular development platforms like Arduino, Raspberry Pi, and other microcontroller systems, thanks to readily available libraries and code examples. Its compact size, durability, and reliable performance make it a go-to choice for projects requiring numeric input or simple control mechanisms.

Features :

Ultra-thin design & adhesive backing provides easy integration to any project
