    The module is ok. If you use it with a low current input, you can control a low range of voltage. I use it to control a 1 w power led . Certainly, the sensitivity is limited but is able to drive the LED between 2 and 3 volts with a 6 volt input about. It is the into of a microscope and I control the mirror rotation and outside light and service.

    I use it with a wall transformer 30 V / 400 ml Amps in DC voltage. The kit goes well (in this case) from 1.5 V to 27 V empty. It can be used for small low power assemblies. However there are two problems, at low voltage there is no display! Between 1.4 V (potentiometer reduced to max.) and 5 V but the current passes! To be checked with the multimeter in this case (or this segment) which allows to make an adjustment. Personally I find that the value of the amperage (2 A.) seems to me very optimistic because at low voltage the circuit heats very quickly and it must dissipate a lot of heat. 500 ml Amperes seems to me more reasonable if we want to keep this kit in good condition. I appreciated the possibility to supply this control circuit with both DC and AC. I tested both.

    The output plug was soldered at an angle but a fast and easy fix with my iron. Works great!. Using it to power my Lipo charger and ocassianally ise it for some testing on smaller low power items...Love the ability to adjust the output. Checked output with my meter and it is right on spec with the display! Super cheap for what you get.
