I think you have posted this earlier in the thread. So, if I understand correctly, I can just get a DIN 3 pin connector (i think thats what jebao uses) and wire up the existing 24v power supply along with pca9685 output, and that should do. ..I did a little testing on a faulty jeboa wavemaker, three wires go into it from controller, there's a constant 24v and the yellow wire varies it's voltage from about 2 to 5v depending on setting
