I needed a Grinch dimmer fast and I wasn’t able to buy a PCB from RPM in a hurry, so I hacked one.
RPM’s Grinch Dimmer
So this is how I made it:
Grinch Dimmer top
next the Bottom – it isn’t as complicated or hard as it may look!
the “Rats nest” on the bottom
I use my on Lay out for the ISP connector. But the standar 2×3 pin header can still be used.

Connections: DMX on the Left and Grinch on the right
