Open-source hardware group puts out vid system-on-a-chip

Both the 5-pin and 3-pin DMX connectors use balanced signaling. The two extra connections on the 5-pin plug are not used (see http://pinouts.ru/Home/dmx-512_pinout.shtml). So, yes, I maintain you can use a simple passive adapter to go to 5-pin if you need to.

The DMX signal is generated by a custom FPGA core (not a hacked UART), which produces a correct break and not a "framing error". Feel free to check our Verilog source (online at Github) if you have the slightest doubt about this. If you can find bugs, we'd be happy to fix them and push out a FPGAs bitstream update.

It is not, and yes our demo videos could/should be a lot better. We have a new one in preparation (yeah, bad timing), but you'll have to trust my word until we get it out, or someone makes a better video.

We chose the 3-pin connector on purpose, because no matter what ANSI says it is what is present on most DMX equipment (except maybe the high-end professional one) so it is convenient for the majority of our users.

If you have the 5-pin connector on your equipment, you will be able to use it with the Milkymist One using a simple passive adapter.
