Review on DROK Controller Regulator Industrial Optocoupler by Ahmed Jackson

Not intuitive board configuration. I lost several hours to get it working. Very little useful information on the web. The data sheet is almost illegible due to poor English. Drok technical support was slow and unhelpful. On most motor controllers, the +5V pin can be used as a power source for the microcontroller. On this board you actually need to provide a separate 5V power supply to the "+5V" and "GND" pins for the signal pins to work. I don't know why they couldn't have a built in buck converter so the board only needed a power supply. This leads to a very chaotic setup. It was incredibly unintuitive, but once I figured out the signal pin's power source, everything worked great. I will definitely buy them again as they are affordable, powerful and now I know how to use them but be aware that there is almost no information about them.
