[hide]Overview
LED tiles are just that, a piece of PCB with five RGB LEDs on them and a single white LED. They use a 16 channel LED driver with a SPI interface so that many can be driven from the same microcontroller. The idea is that you can play with just one, or tile them on a wall or other surface for neat visual effects like fading a color across the surface. The size of the PCB is yet to be determined. Initial prototypes will be through-hole parts, but further revisions will be on real PCBs with SMT parts.
With the current design of 5 independent LEDs per board, pairing is currently the best way to use these, so you get a 5x2 array out of each pair of tiles.
An alternate configuration would be to use 3 drivers on a single board to power 16 RGB LEDs in a 4x4 or 8x2 array.

These two versions may be merged at some point or the version I create may use parts from both.
