I bought several of these because they are far superior to using a normal LM317 linear regulator circuit, and they are less expensive in the end anyway. It would cost me more to buy the components to build a 3A linear regulator circuit (2x LM317, capacitors, resistors, potentiometer, protoboard and a heat sinks) than it cost me for one of these buck ...

Good, nice and compact device. Very usefull in your own microcontroller prodject. You can set the output voltage very good. This output voltage is very stabel. Take care to connect not a higher power input than 32 Volt. Otherwise the device is broke insite and the input come's direct to the output. On a lot of microcontroller and robotic prodject's ...

Simply and sturdy board for DIY aplications, ideal to branch to a 12-24V line and reduce to 5 or 3.3V MCU application. Just branch and adjust the tension using the potentiometer. Limited to 2.5 A, means that you must have that current limitation in your proyect. Not sutable for motors or other stuff, but it can be very useful for install a led bar in ... Read more
Rugged construction, all components are firmly placed on PCB, the circuit is a combination of common & SMD components,
Multi-turn Potentiometer for precision voltage output adjustment, does have two screw holes on PCB for placement, input and output pads are well arranged and easy to work with. None.
By consuming at stand by operation about 80mA ... Read more
Very good quality! I enjoy this product. Sheap, small, but working very good! Now I controlling voltage from my robotics tank. In my country this product selling for $5. -----------------------------------------
??? ???????? ????????????! ??????? ????????! I don't show. Everything works fine. I tested 1.5 hours under a load of 1 Amp.
