Great little PWM module!
Awesome little module that handles SS well, great for controlling small fans/motors. There could be two minor improverments:1) The led indicator is SMD, in a weird location next to the pot (looking down on the board). Great as an indicator when testing but useless if mounting in a case. If there was headers for an LED is would be better.2) The terminals are pre-soldered to the board - again ideal for quick/ease, however when using the board in a case/perm fixture I would de-solder this in fav of soldering the connections directly to the board. You find lots of modules come with the header terminals but you have the option of soldering.Apart from that it works really well, extremely well for the price!

Perfect
Worked perfectly really easy to use and I was able to screw it into a suitable place easily. Also low profile enough to quietly fit into my set up

As described
Works very well. Beware, the connection markings are underneath the board, so bear in mind when locating

Can use a 5v usb-A charger as a power supply for fans.
5V usb supply into this module then a 12v fan yields great results.Controller and knob moves smoothly and mounts easily with included nut.With this simple setup, the fan is able to operate through a full range of RPM'.LED power indicator built into the PCB is nice and bright. It is easily visible when I poked a pin hole next to it and works nicely with a blob of semi-transparent sealer / glue to act as a diffuser.Good value items for your home project.Have since acquired more.

Good
Good value and do the job required of them.

Very adjustable
I wanted an adjustable motor to run a model windmill. I’ve tried others unsuccessfully before trying these. The adjustability is really accurate ranging from extremely slow rotation to very fast so there’s plenty of range to finely tune the motor to the perfect speed.

Works but only from about 8 to 12.4 Volts
Built quality is OK. Price is good. Not sure why they need to ship 2 as its a bit of a waste but I guess it means I've got a spare. FYI there is only one cable shared between the two units, not that it should matter... cut it etc... ;)But real issue is it only provided 7.9 (ish) to 12.4 Volts. So rather than "Duty cycle adjustable 0%-100%" I would say its "64%-100%" and so I'm giving it 64% out of 5 stars... I say "ish" because the DC voltage was rapidly fluctuating between 7.8 and 8 suggesting its not stable.However for my application which was to drive a silent fan in an extractor assembly it was adequate and the price is peanuts. But with hindsight I'd go for a more expensive one that's proven to do the 0-100% range.

Does the job
Unfortunately one just didn't work, had to get a refund and then order again. Great that it comes with the wire and they now work perfectly.

Fonctionnement
Fonctionne très bienMais le moteur DC 3V-6V s'arrête au bout d'une ou deux minutes, même à vide, sous 4.5V ! Pourquoi?

Verkar bra!
Ser bra ut men ej testade!

Absolut top auch fürs Dimmen von LEDs
Die Artikelbeschreibung erwähnt es ja nicht ausdrücklich, aber auch für das Dimmen von LED-Ketten und LED-Filament ist dieser kleine Helfer die erste Wahl. Ich habe die Schaltung mit 12-Volt-LED-Ketten (COB) und 3-Volt-LED-Filament im Einsatz und kann nur sagen: Plug’n’Play vom Feinsten! Dass das hochwertige Poti dann auch noch mit einem On/Off-Schalter ausgestattet ist und alle Teile zur Befestigung mitgeliefert werden, macht das Set aus meiner Sicht perfekt. Also ich kann nur sagen: Ein Top-Produkt zum unschlagbaren Preis, volle Punktzahl.

PERFECTO PARA REGULAR MOTORCILLOS DE MANUALIDADES JUGUETES CASEROS
Perfecto para manualidades de los niños, pudiendo instalar el potenciómetro o regulador de voltaje para calibrar la velocidad del motorcillo. En mi caso,hace variar la velocidad de una bola del mundo giratoria. Perfecta función y fácil de instalar. Viene con cables de repuesto o accesorios para poder instalar a motor y a pila/fuente de alimentación.

Piccolo circuito, completo e ben realizzato
Funziona perfettamente ed è facile da installare. In prossimità dei connettori è indicato anche dove colegare i cavi di alimentazione e dove collegare i cavi del motorino. Viene spedita una confezione che contiene 2 regolatori di velocità singolarmente impacchettati. Per ciascun regolatore di velocità sono inclusi nel prezzo anche una rondella e un dado per il fissaggio e una manopola di plastica esterna per la regolazione. Oltre a regolare la tensione, il pezzo funge anche da interruttore. Sul circuito è presente anche un micro led rosso che si ilumina quando vi è alimentazione. Davvero un ottimo prodotto.
