Bring a little bit of Times Square into your home with this 16 x 32 RGB LED matrix panel. These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips. We thought they looked really cool so we picked up a few boxes of them from a factory. They have 512 bright RGB LEDs arranged in a 16x32 grid on the front. On the back there is a PCB with two IDC connectors (one input, one output: in theory you can chain these together) and 12 16-bit latches that allow you to drive the display with a 1:8 scan rate. These displays are 'chainable' - connect one output to the next input - but our Arduino example code does not support this (yet). It requires a high speed processor and more RAM than the Arduino has! These panels require 12 digital pins (6 bit data, 6 bit control) and a good 5V supply, up to 2A per panel
