This is the NeoPixel Shield from Duinofun. This Arduino shield is equipped with 40 WS2812 RGB LEDs arranged in an 5x8 matrix with on one pin (Digital #6) needed to control them all.
Each shield is powered by the 5V onboard Arduino supply and as long as you aren’t lighting up all the LEDs full power white that should be fine. You can also solder in the included terminal block to attach an external 4-6VDC power supply in case you need more power than what the Arduino provides.
Additionally, you can chain as many of these panels together as you’d like when tiled separetely from the Arduino. For the second panel, connect the DIN connection to the first panel’s DOUT, connect the ground pins together and power with 5V. It should be noted that after five or more panels you may run low on RAM if you’re using an Arduino Uno.

Jargon buster
Plain-language definitions for the technical terms used above.
- DIN
- As a pin label, DIN stands for 'data in', the input through which a device receives serial data from a controller, as found on SPI displays, LED drivers and other serial modules. DIN can also refer to the German standards body of that name, as in a round multi-pin DIN connector or DIN-rail mounting.
- 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.
- 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.
- RAM
- RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- 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.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- Terminal block
- A terminal block is a connector that joins wires together in a neat, removable, or serviceable way, usually clamping each wire under a screw or spring instead of soldering. It makes it easier to connect, change, or service wiring without permanent joints.
