The NeoMatrix 8x8 RGBW LED Matrix – Warm White features 64 individually addressable NeoPixels with RGB + white output, 800KHz control, and simple 5V wiring for bold, high-current lighting projects…and more!
Put on your sunglasses before wiring up this LED matrix — 64 bright RGBW LEDs adorn the NeoMatrix for a powerful mix of colour and white light. Arranged in a 8x8 grid, each pixel is individually addressable, and only a single microcontroller pin is required to control the entire panel.
This is the Warm White RGBW version. We also offer this NeoMatrix in Natural White, Cool White, and classic RGB.
Each NeoPixel is ‘split’: one half provides the familiar RGB output, while the other half is a white LED with a yellow phosphor coating. Unlit, it resembles an egg yolk. When powered, the LEDs are extremely bright and can be controlled with 8-bit PWM per channel (8 bits × 4 channels = 32-bit colour per pixel), making them suitable for projects that need both saturated colour and clean white illumination.
Wiring is straightforward. The board includes two 3-pin connection ports. Solder wires to the input port, supply 5V DC to the +5V and GND pins, and connect DIN to your microcontroller. If you’re using the Adafruit NeoPixel Arduino library, digital pin #6 is commonly used. Be sure to connect the power supply ground to your microcontroller ground. Each LED can draw up to 60mA, meaning a single panel can require up to 3.5A if all LEDs are set to bright white. For most applications, expect around 1–2A per panel. A 5V 2A supply is suitable for moderate brightness use.
If you need larger displays, panels can be chained together by connecting the DOUT of the first panel to the DIN of the next. Also connect 5V and GND between panels. You can chain multiple matrices together, although with four or more panels you may run low on RAM if using an Arduino UNO. Monitor your total power requirements carefully — larger setups may require a 5V 10A power supply.
NeoPixels use a single-wire 800KHz protocol with very precise timing requirements. Because of this, a real-time microcontroller such as an AVR, Arduino, PIC, mbed, or similar is required. They are not suitable for Linux-based microcomputers or interpreted microcontrollers such as Netduino or Basic Stamp. An 8MHz or faster processor is required. The Adafruit NeoPixel library supports these RGBW pixels on AVR cores, and other platforms may have compatible ports available.
Supplied as a single 8x8 RGBW NeoMatrix panel, fully assembled and tested.
