Keyestudio 40 RGB LED WS2812 Pixel Matrix Shield for Arduino

The Keyestudio 40 RGB LED WS2812 Pixel Matrix Shield for Arduino is a stackable expansion board designed to bring vibrant, programmable lighting to your Arduino Uno projects. It is ideal for students, educators, and makers looking to explore digital art, custom displays, or visual feedback in their robotics builds.

Stackable Arduino Uno compatibility

Designed to plug directly into an Arduino Uno, this shield features a stackable design that preserves access to your microcontroller's pins. It integrates 40 individually addressable WS2812 RGB LEDs into a compact matrix.

Integrated 5050 SMD components

Each pixel on the matrix is a 5050 SMD component containing both the control circuit and the RGB chip. This integration provides a large scattering angle, high brightness, and excellent colour consistency across the entire display.

Built-in signal reshaping circuits

The shield includes an internal signal reshaping amplification drive circuit to prevent waveform distortion from accumulating as data passes through the matrix. This ensures reliable communication even when cascading multiple pixels.

Robust circuit protection

An onboard anti-reverse protection circuit prevents damage to the internal ICs if the power supply is accidentally reversed. The board also features built-in power-on and power-down reset circuits for stable operation.

High-speed single-wire communication

Using a single NZR communication mode, the shield achieves data transmission speeds of up to 800Kbps. At a refresh rate of 30fps, you can cascade up to 1024 pixels with a transmission distance of up to five metres between points without needing extra circuitry.

True full-colour display

Each of the three primary colours supports 256 levels of brightness, enabling a full spectrum of 16,777,216 colours. With a scan frequency of no less than 400Hz/s, the matrix delivers smooth, flicker-free visual transitions.
