The NeoPixel Mini PCBs are among the smallest addressable RGB LED breakouts available. Each tiny board measures just 8 × 10 mm and features two sets of three solder pads on the back for easy wiring. The pixels are chainable — you only need one digital pin to control as many LEDs as you like.
Each NeoPixel includes a built-in constant-current driver, providing full 24-bit colour with automatic PWM. The constant-current design means the LEDs maintain consistent brightness even as battery voltage fluctuates. Using ribbon cable, pixels can be spaced up to approximately 150 mm (6″) apart before signal integrity becomes a concern.

Jargon buster
Plain-language definitions for the technical terms used above.
- Colour depth
- Colour depth describes how many different colours a display can show. A 65K-colour display can show about 65,000 colours, which is useful for icons, graphs, and simple full-colour interfaces but is less detailed than modern phone or computer screens.
- constant-current driver
- A constant-current driver supplies a set current even as the load voltage changes. For a TFT backlight, this helps keep brightness stable and prevents the LEDs from being overdriven.
- 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.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- 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.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- 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.
