DFRobot Gravity: 8×8 RGB LED Matrix – Flexible WS2812B LED Panel

Features

Full-Color 8×8 RGB LED Matrix: This addressable RGB matrix features 64 individually addressable SK6812/WS2812 LEDs (5V) supporting 16.7 million colors (256 brightness levels per RGB channel) and 400Hz refresh rate for fluid animations on your 8×8 RGB LED matrix.

Plug-and-Play Gravity Interface: This WS2812B LED panel includes a pre-soldered XH2.54 3-pin connector (DIN/5V/GND) which ensures direct compatibility with Arduino I/O shieldsno soldering required for your Arduino LED display projects and flexible LED matrix setups.

Cascading Control: Chain multiple addressable RGB matrix units via DINDOUT daisy-chaining; control entire arrays with one microcontroller pin to create a larger flexible LED matrix using this WS2812B LED panel.

Robust Design: Flexible PCB withstands bending; this 8×8 RGB LED matrix operates in -25C to +80C environments. Dimensions: 8080mm (3.153.15″), weight: 130g. This flexible LED matrix is ideal for portable designs.

Technical Specifications

Power & Connectivity

Included Accessories:

Matrix Gravity Interface Cable (3-pin XH2.54 to Dupont) for 8×8 RGB LED matrix

DC Barrel Jack Adapter (Female) for external 5V power injection into your WS2812B LED panel and addressable RGB matrix.

Power Advisory: For multi-matrix setups using an addressable RGB matrix, use external 5V power via the Gravity expansion boards servo port to prevent microcontroller overload in your Arduino LED display.
