Review: Works very well but bear in mind there is are no instruction information. - These units work well but you are going to struggle a bit to get them working. First they are incredibly small which means the writing and solder pads are tiny too. Two ways of operating: By using the tiny variable pot, to adjust which voltage you select but this is where it gets tricky! The VAR setting is the default EVEN THOUGH THERE IS NO SOLDER BLOB over the pads for that! (Remember only one voltage can be used/selected) So ignore the VAR solder blobs and carry on by adjusting via the micro pot, your voltage. If you want to select a voltage as a FIXED entity you must crape away the little track round the top of the VAR blob! This kills the micro pot from interfering with your selected voltage. Remember to solder a blob over the small gap in your selected voltage.
Review: Good quality - Works well

### ⭐⭐⭐⭐ Tiny versatile buck regulator PCBs at an excellent price.
*by G***S on 6 March 2024*

Excellent little boards which can be used with the onboard potentiometer to set the output voltage or by cutting the track to it and using one of the fixed resistor solder bridges as discussed elsewhere and shown in my attached photos. If you cut the track, you can always restore the potentiometer using the top solder bridge. The EN (enable) connection can be left open circuit to let the onboard pull-up enable the output or shorted to ground using a mechanical switch or FET for output control e.g. from a voltage monitor on the input. With the track cut and the 5V bridge soldered, the output was stable from an 18V all the way down to 5.4V input with a ~ 500mA load. Marked down slightly as there was no need to have a track to cut given the presence of the solder bridge for the pot.
