:*I decided to connect the LEDs to the drivers sequentially, so R0 -> OUT00, G0 -> OUT01, B1 -> OUT02, etc. This was partially prompted by designing [[Media:DDF-PCB-v1-20110403.png|a PCB]] for future use. I hope to have a prototype of the board produced professionally, so I can test and refine it. A future version of the board will have the microcontroller embedded (as described below), or ''possibly'' done as an Arduino shield. Turning it into a shield is unlikely, however: the board would be quite large, and routing might be complex. It would likely be more than my version of Eagle can handle! | :*I decided to connect the LEDs to the drivers sequentially, so R0 -> OUT00, G0 -> OUT01, B1 -> OUT02, etc. This was partially prompted by designing [[Media:DDF-PCB-v1-20110403.png|a PCB]] for future use.

:*The prototype PCB has arrived, but I'm not sure it will be the final design. Might be worth playing with, however. Perhaps I will solder it with chip holders instead of soldering the chips directly. | |||
:*I have also considered the merits of having an onboard 4-port USB 1.1 hub and thinking about autodetecting module relative position and orientation | |||
