I was able to get it to work on an SBReeflights BB, though it only has a 3 wire interface to the driver and the voltage was from a separate supply inside.Re-reading over the 193 pages of posts, it looks like 4 people have tried the black box leds with varying degrees of success. Did anyone ever figure out how to get them to dim/ramp without buzzing noises, and smoothly go between values on the reef pi slider? Here are pictures of my black box leds. I can't tell if people are sending the vdim+ / - signals from the pca9685 digitally or with an analog converter. Do we have a fritz diagram for the black boxes with 4 wires? Did we decide we need a 12 volt or 10 volt power supply, and does it require a voltage regulator to drop from 12 to 10. The black box posts are very confusing. Please help.
Thanks!!!
Can you pin it out and see what voltage is on the V+ pin and see if any are tied together as common GND.
Here is my fritzing diagram and some images with it. I did use a regulator to drop from 12v to 10V.
I am currently not using the on/off feature for each driver, rather using a relay to turn the entire light system off.
Here is the circuit (before I removed the RC filter)
