Create your own custom input device with this 4×4 keypad from Waveshare!

The keypad features 16 tactile pushbuttons arranged in a 4×4 layout. The pin header is pre-soldered and labelled to help you write your own programs. There are also mounting holes for adding to your project/enclosure.

Please note that there isn’t a pin per button for simple GPIO connections – code will need to treat this like a matrix (see examples in the link below).

You might need some jumper wires or a breadboard to go with it!
