Large 32 x 16 RGB LED Matrix Display for Arduino Projects

Create large message boards or displays

A large Matrix LED display which comprises of 512 RGB (Red, Green and Blue) LED's suitable for message board, shop displays, clocks, etc Arduino projects. Features bright LED's which can be seen over 20 metres away. The controller IC is integrated on the board loaded with compatible library. Housed in a rigid and tough plastic frame. Use multiple matrix LED displays to create a bigger visual display. 

Specification:

• 32 x 16 high brightness RGB LEDs (512 LEDs total) on a 10mm pitch
• 5V operation
• Viewable over 20 metres away
• Tough plastic frame
• Controller IC's on board, simple clocked data interface
• Arduino compatible library, graphics functions and example support
• Dimensions: 320(W) x 160(H) x 14(D)mm (including rear connectors)
