It will be printed in the pcb.

You need to short out the legs of R20 and R22.
Make sure to move the jumpers too, so you get PWM signal. The marking in the board is wrong though.
It should read PWM/Analog instead of Analog/PWM

Got it. I'll probably be doing this project this weekend.

Thanks!

Update!

I've been running these for a few months now.

I have 8 LDD drivers running open-air on top of the canopy. They run hot, but much less than the rated max. I used a Genssi 48V DC 7.3A 350W Regulated Switching Power Supply from Amazon. I've had no problems, but the fan is kinda noisy when it switches on.

LED list is as follows (all Cree):

RB x32
Blue x8
UV x10
NW x10

No lenses. Lights 6-8" off the water. I have a Crocea clam on the bottom which is doing great, as well as a ton of LPS at all levels. I have a soccer ball sized green pavona mid level towards the back. Zoas, softies, etc. Everything is doing well. I'm going to load up the acclimation code and try some more SPS.

I used the Rapid LED driver boards. I don't recommend them. They use a spring-loaded connector which doesn't hold the wires very well. I'd much rather have the screw down kind.

Thanks for all the input! I'll try to get a FTS after the lights come on.

Lee: Thanks!

Pandimus: You replaced the built-in fan? There's a thought.

Yep, it plugged right in and considering its a bigger fan it spins slower and creates more air...just a bit more bulky
