4 x 4 Matrix Array 16 Key Membrane Switch Keypad Keyboard for Arduino/AVR/PIC

The keyboard is a key element of a microcontroller system that can assign tasks to perform, enter data, and interact with the machine. This has a layout of a key matrix that allows you to efficiently leverage the microcontroller pins. The 16 keys can be mapped using only 8 microcontroller data pins, making the programming very slim and simple to implement. The very small thickness allows you to install it comfortably and easily on any device.
