LM2596S DC-DC Buck Converter DIY 4-40V to 1.25-37V Step-Down Regulator Power Module Volt Stabilizer with LED Voltmeter Display

heat level

I Connected a 32v lightweight Mighty Jump automotive Jumper battery to my tank frame Arduino Robot. their product allowed me to lower the 32v down to 11.1v so my robot has a function time of 40 min compared to 10 min the other 11.1v battery pack was giving me. just know when the battery starts to give out less volts its output drops volts too. make sure power supply is fully charged before setting the output

poor quality construction. it looks identical to others on amazon, but isn't. took the advice from a reviewer and bought a pair for $2 more. be careful connecting the wires. no reverse polarity protection. burned up this one and one of the other pair i ordered.

Got this so I could run fpv on my rc truck. Works exactly as it should easy to adjust, and love the read out.

If this was just a step down fine but I needed it to control a planetary gear motor. When run on the bench power, the motor would adjust in speed with the voltage. This did not happen. I was looking for a digital PWM Speed controller (which this item came up in that exact search)

The unit has been installed now a few weeks. So far, there hasn't been a problem with it. This review can change depending on how long it works well. I will attempt to update this review in a few months pending the viability of it's operational status.

The buck converter worked great, used it to lower the voltage from 19v to 12v in my amplifier project

Muy bien el producto, las indicaciones de ajuste final de voltaje están muy bien explicadas. Felicitaciones!

It works

I've got the same but with one button, it does the job so its good

I received totally different part!!
