Hi guys,  
there is another topic open rgd. porting a DMX library to Spark:

> Hi Guys, for some reason I would like to integrate a Spark Core intoo a DMX light controller. Currently I use a case with integrated power supply so all you need is to plug in power and DMX. As we use another DMX controller for simple light...

The hardware to create a (not-isolated) DMX-Port is quite simple. The isolation can be done by some optocoupler, but as we're using isolated AC/DC power-supplies and WiFi it would be safe to build a non-isolated DMX-interface.

If you still want to connect your core to other peripherals or a computer I'd higly recommend to implement a isolated interface.

regards
