16x16 WS2812B addressable matrix

These are awesome 16x16 individually addressable RGB matrix panels. Composed of 16 columns x 16 rows of WS2812B (WS2812/WS211 protocol) individually addressable LEDs on a flexible PCB, these panels have 256 LEDs and they can be daisy-chained to make bigger signs or panels!

The basic specs for these panels:
- 256 WS2812B chip-on-die LEDs arranged in a 16 x 16 matrix
- Individually addressable LEDs
- Full 24 bit color
- 5v operation
- LEDs take data in green, red, blue order.
- WS2811 Datasheet available at http://www.insomnialighting.com/datasheets/WS2811.pdf
- IMPORTANT INFORMATION about using the WS2812/WS2811 LEDs can be found at http://www.insomnialighting.com/datasheets/WS2811RGB_WS2812_manual.pdf - PLEASE read this!

These LEDs are a bit different than the standard WS2801 ICs, these do not use separate clock and data lines. Instead, the data line uses a protocol where a digital "1" is sent by raising the data line high and holding it, and a "0" sent by raising the line high briefly and then returning it to low.
