Ok, pas testée, semble conforme
Very good electronic module, thanks.
Very good module, with R1 you can change output voltage, also energy conversion is very high, thanks.
Item as soon as possible, it's time. Why you're so scared. The product is according to the description, works perfectly and arrived within the expected time.
Excellent condition.
Very good quality, excellent efficiency good price
A very useful module for new developments & experiments. In case of positive results of experiments - more units will be ordered! Very satisfied.
an excellent module for an uncomplicated power supply
Seem fine.
To alter the voltage output requires the exchange of a surface mount resistor which is very tiny. _The unit received indicated 12volt output but in fact measured half that._To adjust the output needs a very steady hand with a suitably designed soldering iron and a keen eye to remove the original resistor and replace with the required value. If adjustment is further required - lifting of the track could easily occur._A trimpot should have ideally been part of the design.
