I have developed 3 boards that I will be releasing as open source. #1 is a pixel driver, 1-4 universes of DMX512 in via 2 RJ-45 connectors, 16 pixel string outputs via 4-pin headers, same connector and pinout as MPH's boards. Supports 2801 and 6803 pixels. Can be a mix of 5V and 12V strings, a mix of 2801 and 6803 strings, various lengths, etc. >200hz refresh rate of the strings. #2 is a converter to convert between E1.31 (DMX over ethernet) and standard DMX512. 4 Universes in and out. The current version is for E1.31 in and 4MX512 out, but the same board, with an IC swap and a couple of jumper changes, and some new software, can go the other way. The original plan was to use boards 1 and 2 together to drive pixel strings from E1.31, but I was eventually able to get both functions on one board, so #3 is a pixel driver with E1.31 DMX over ethernet in, and 16 pixel string outputs. All boards are 2.5"x3.8". I have working prototypes of all 3 boards. If there is interest I will post some pictures and additional specs.
