Matrix Key Board 4×3 (12 Kyes) & 4×4 (16 Keys)

Product Description: Matrix Keyboard 4×3 (12 Keys) & 4×4 (16 Keys)

The Matrix Keyboard 4×3 (12 Keys) and 4×4 (16 Keys) are compact, high-quality keypad modules designed for easy integration into a variety of DIY electronics projects, embedded systems, and automation applications. These keypads feature a simple 4×3 or 4×4 matrix layout of tactile push buttons, making them ideal for creating custom user interfaces in Arduino, Raspberry Pi, and other microcontroller-based systems.

The 4×3 Matrix Keyboard includes 12 keys arranged in a 4×3 grid, while the 4×4 Matrix Keyboard has 16 keys in a 4×4 grid, allowing for more input options and versatility in design. These keypads are commonly used in security systems, alarm panels, control panels, and home automation projects, where user input is needed for specific functions.

Both versions use a simple, cost-effective matrix scanning technique that reduces the number of required I/O pins on a microcontroller, providing a compact and efficient solution for user input. The keys are made of durable tactile switches, providing tactile feedback when pressed, ensuring reliability and accuracy during operation.
