uDMX-mod is a modified hardware compared to the original uDMX by anyma.ch.

Changes are:

• No smd parts are used (easy to solder)
• additional galvanic isolation (security for your computer)

In my sheet i used the optocoupler HCPL-4100 as i got lots of them. You can use the more common 6N137 instead. Have a look at the FAQ to see how.

Board and sheet are created by freeware version eagle. Here you get those eagle files.

Photos, board and sheetshould be enough to build uDMX-mod. Try the animated gif to find positions of all parts if you use a breadboard.

PLEASE NOTICE: Tho top side is shown mirror-inverted. It helps finding the position. For exact rotation of the parts use the not animated gif.
