    LM317-based step down converter. The potmeter allows you to adjust the voltage precisely. It works well. The circuit is compressed onto a tiny PCB so it is easy to add to any projects since it does not take up large volumes.

    Good quality price. It's the second time I've ordered this product since the primire is placed in a current transformer and regulates from 1.3 volts to 24 volts. It works pretty well. I have other projects that I will use.

    One of them exploded because my stupid ass connected it backwards. Worth it just for the explosion. OH and the other two work just fine
