4x4 Matrix Button Keypad Module


In the application system of the microcontroller, a keyboard is essential in human-machine communication. If a button is short, you can connect one to the controller's I / O port; but when you need a large number of buttons with limited I / O port resources, this 4x4 Matrix Keypad is undoubtedly your best choice. The 4x4 matrix keypad is the most common keypad format.

The key layout is in matrix format, so you can define only eight I / O ports and 16 buttons and save multiple I / O port resources.
