Put on your sunglasses before wiring up this LED matrix — 64 eye-blistering RGBW LEDs adorn the NeoPixel NeoMatrix for a blast of configurable colour and white. Arranged in an 8×8 matrix, each pixel is individually addressable with just one microcontroller pin, delivering 32-bit colour (8-bit PWM per channel across four channels).
This is the Warm White (~3000K) version, producing a soft, cosy warm tone ideal for ambient and decorative lighting. Each RGBW LED is split — one half is the familiar RGB, the other is a white LED with a yellow phosphor. Also available in Natural White (~4500K) and Cool White (~6000K).
Key Features
- 64 RGBW LEDs – 8×8 individually addressable matrix with warm white (~3000K) dedicated white channel
- 32-Bit Colour – 8-bit PWM per channel (R, G, B, W) for fine-grained colour and white control
- Single-Pin Control – One data line drives all 64 LEDs using the NeoPixel protocol
- Chainable – Connect DOUT of one panel to DIN of the next for larger displays
- Two 3-Pin Ports – Input and output connectors for easy daisy-chaining
Power Requirements
- Supply voltage: 5 V DC
- Maximum draw: ~60 mA per pixel (up to 3.5 A per panel at full white)
- Typical draw: 1–2 A per panel during normal use
Note: RGBW NeoPixels require RGBW-specific library support. Using a standard RGB NeoPixel library will produce incorrect colours. Ensure your library is configured for RGBW (SK6812) mode, with 4 bytes per pixel (256 bytes total for this panel).
Wiring
- Connect 5V and GND from your power supply to the input port
- Connect DIN to a digital pin on your microcontroller (pin 6 recommended for Arduino)
- Ensure a common ground between the power supply and microcontroller
- To chain panels: connect the first panel's DOUT to the second panel's DIN
Tip: When chaining four or more panels, you may run low on RAM on boards like the Arduino Uno (4 bytes per RGBW pixel). Consider a board with more memory for larger installations.
Compatibility
- Works with real-time microcontrollers: Arduino (AVR, SAMD, nRF52), ESP32, ESP8266, Teensy, and more
- Requires 8 MHz or faster processor
- Supported by Adafruit's NeoPixel library (Arduino) and CircuitPython/MicroPython
neopixelmodule - Not compatible with Linux-based SBCs or interpreted platforms (e.g., Basic Stamp) for direct driving
Ideal For
- Warm ambient and decorative lighting
- Colour and white LED signage and displays
- Wearable electronics and costumes
- Interactive art installations
- Multi-panel tiled displays

Jargon buster
Plain-language definitions for the technical terms used above.
- AVR
- AVR is a family of 8-bit microcontrollers used in many classic Arduino-style boards. If a USB host library mentions AVR support, it suggests the examples or compatibility may be aimed at those older microcontroller boards.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- DIN
- DIN means data in, the pin where this display receives data from the controller. Connecting DIN to the correct SPI data output pin is needed for the screen to receive pixel and command information.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- 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.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- 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.
- 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.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- 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.
