Keypad 4x4 Matrix

The Keypad 4x4 Matrix is a versatile and user-friendly input device that is compatible with Arduino and Raspberry Pi. This keypad provides a simple solution for projects that require numerical input, such as security systems, telephone applications or electronic locks. With its 16 keys arranged in a 4x4 matrix, it allows for a compact and efficient user interface. The keys have a pleasant pressure point and are easy to operate thanks to the low contact resistances of less than 100 ohms. The module is small, lightweight, and easy to install with four mounting holes in the corners. Communication with the microcontroller is carried out via just 8 pins, simplifying integration into projects.</p>
