4x4 Matrix 16 Button Module

Product Description:
The 4x4 Matrix 16 Button Module is a compact and efficient keypad solution designed for microcontroller and electronics projects. It features 16 tactile buttons arranged in a 4x4 matrix layout, allowing multiple button inputs while using a minimal number of I/O pins. This makes it ideal for projects where pin availability is limited.

The module is commonly used with Arduino, ESP32, Raspberry Pi, and other development boards for applications such as password systems, access control panels, calculators, menu navigation interfaces, and DIY control systems. Each button provides a clear tactile response, ensuring reliable input detection during operation.

Its simple matrix wiring design allows easy integration using standard keypad libraries, reducing development time and simplifying coding. The compact size makes it suitable for breadboard prototyping as well as permanent installations in enclosures and control panels.

This keypad module is well suited for educational environments, robotics projects, embedded systems, and hobbyist electronics, offering a practical way to handle multiple user inputs in a structured and efficient manner.
