Sneak peek: white 32x16 LED Dot Matrix Display panel for Arduino

Our red 32x16 LED Dot Matrix Display Panel for Arduino has been very popular, but we've always wanted to do other colours too. Unfortunately the economics of LEDs means that red is by far the cheapest to buy, and when each panel has 512 LEDs even a slight increase in per-LED price has a big impact on the build cost. Nevertheless we really want to do it, so we prototyped a few other colours including yellow, blue, green, and white.

We gave a white prototype to our friend John Boxall of Tronixstuff fame, and he's made a funky video showing how cool it looks:

In the YouTube description John says:

"This example is being powered by the Arduino and therefore at low brightness. It was too bright to film when using external power - my camera just couldn't deal with the sheer intensity of the display. You have to see it to believe it."
