The 4×4 Matrix Keypad Module consists of 16 tactile buttons arranged in a 4×4 grid, offering a total of 16 unique key positions. Each button press corresponds to a unique combination of row and column connections, allowing for easy integration with microcontrollers like Arduino or Raspberry Pi through digital input pins.

Designed for simplicity and ease of use, this keypad module typically employs a matrix scanning technique to detect key presses. The matrix arrangement enables the reduction of the number of required input pins, making it efficient for interfacing with microcontrollers that have limited available pins.

Whether you’re working on a DIY electronic lock, a user interface for a project, or any application requiring input from users, the 4×4 Matrix Keypad Module offers a cost-effective and reliable solution. Its compact size, ease of integration, and versatility make it a popular choice for hobbyists and professionals alike.

Enhance your projects with user interaction and data entry capabilities using the 4×4 Matrix Keypad Module – a fundamental component for creating responsive and interactive electronic devices.
