A single unit provides 128 keys and 128 LEDs, suitable for projects such as control panels, custom keyboards, launchpads, gaming input devices, and interactive installations. The accompanying Arduino library encapsulates the underlying communication procedures. Developers only need to use a small number of interfaces to complete key scanning and LED control, greatly lowering the barrier to entry. The video below shows a demo I created using a Raspberry Pi Pico with the Keypad module.
