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.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- 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 is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
