Review on 🔌 Qunqi 5pack MP1584EN Ultra Small DC-DC Step-Down Adjustable Module Buck Converter - 3A Power Supply for Arduino, Supports 24V to 12V, 9V, 5V, and 3V by Matt Simpson

I use these MP1584EN voltage stabilizers in projects all the time, this particular version (or clone) sold here is TERRIBLE. The picture in the description doesn't even match the version I received, but in principle the version with the DSUN stamp is bad, the version with the MH stamp works fine. Both boards test fine, but once you solder them into the circuit the DSUN version will fail. I bought these 5 packs and 3 of them broke after soldering, not sure if the soldering temp kills them or what, but I soldered a MH into the same circuit and it works. Buyer Warning. I've attached a picture showing the subtle differences.
