Parts for DMX/MIDI Lightboard
Microcontroller
DMX Interface
1x
Neutrik NC5FP-1 5-pin female XLR panel-mount jack - Standard connector for DMX
1x
Neutrik NC3FP-1 3-pin female XLR panel-mount jack - Some cheaper DMX gear uses 3-pin XLR connectors. I'll include both on my board so I don't have to fuss adapters.
1x
MAX485EPA+ Driver Chip - Industry standard, supposedly more reliable than the TI
SN75176AP chip I've used for previous DMX projects. Also almost 5x the price...
MIDI Interface
3x
Neutrik NYS325 5-pin panel-mount DIN connectors - Standard MIDI connector. Although I only plan on using MIDI OUT to begin with, I'm building in full MIDI functionality including IN and THRU.
Optoisolators (Any of these should work, but different specs called for different models and they're cheap, so I figured I'd mess with a few):
Resistors:
220K
270K
NPN Transistors (Again, I only need 1 and I think either should work):
Diodes:
TI
SN7404N Hex Inverter - do I need it? Maybe not with Arduino...
Controls
Putting it all together...
