Keypad 4×4 Matrix
The Keypad 4×4 Matrix is a versatile and user-friendly input device 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 4×4 configuration, it offers a compact and efficient user interface. The keys have a pleasant actuation point and are easy to operate thanks to the low contact resistance of less than 100 ohms. The module is small, lightweight, and easy to install thanks to four mounting holes at the corners. Communication with the microcontroller is done via just 8 pins, simplifying the integration into projects.
