Review on 🔌 DROK DC Buck Module, Adjustable Voltage Regulator Step Down Converter 6V-32V 30V 24V 12V to 1.5-32V 5V 5A, LCD Power Supply Volt Reducer Transformer Board with USB Port, Protective Case by Chad Jeffries

This buck converter module was purchased for use in a project. It arrived quickly and looked good, but for some reason I can't calibrate the current. I've followed the instructions in the item descriptions (and also downloaded the user manual) and I'm still unable to perform the current calibration. Maybe because I'm using the USB port? No idea. The voltage is perfectly calibrated, everything else works perfectly. I'm not sure if I have a bad block or if I'm doing something wrong. It's supposed to be a constant current mode, but I don't see a way to switch between modes and make adjustments, as mentioned, the instructions aren't very clear. Due to the possibility of user error, I still give this item four stars because it looks good and performs other functions properly. This item is a bit, I'm updating my rating to 5 stars, I figured out what I was doing wrong and how to use it, and it really works exactly as it should. Definitely not a defective item, it was 100% user error. Overall very satisfied, even after asking questions the seller quickly called me back to try to help and answer my questions which was nice too.
