A translucent silicone rubber button pad with 16 buttons in a 4×4 grid. Each button has a hole underneath that accepts a standard 3 mm or 5 mm LED, allowing you to backlight individual buttons with any colour — including RGB using tri-colour LEDs.
The pad can be split into four separate 4-button sections. Each button has a conductive circle on the underside for creating switch contacts with exposed PCB traces. Activation force is 190–210 g, providing a tactile feel similar to a TV remote.

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- MIDI
- MIDI is a standard way for electronic instruments, controllers, and software to send musical control messages such as notes, velocity, and timing. If a board supports MIDI, it can be triggered from keyboards, drum pads, sequencers, or other music gear rather than only from buttons or code.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
