LED matrix displays are a great way of showing everyone what's happening in your embedded project.
The LDP-6416 is a dual-LED, tri-colour 64 pixel by 16 pixel LED matrix display with 5mm pixels 7.62mm apart. Each pixel consists of a red and green LED (commonly referred to as “1R1G”). There are 1024 pixels and 2048 individually addressable LED elements. It includes shift-register circuitry such that all 2048 LEDs can be controlled with only 10 microcontroller I/O lines. Pixels can show as black (that is, completely unlit), red, green or orange (red+green).
The board comes with a 16-way IDC connector and power cable.
