Nice little circuit board
Sure would be nice if the sent some sort of tech documentation. It’s good for basic circuits, but you have no data on it’s exact specifications.

Voltage Backed Protection? Nope...
I order a batch of these power supplies to use in a battery monitoring sensor set up. The project board shows the power supply (top left), voltage sensor, NodeMCU, temp/pressure sensor, and OLED display. The power supply inputs, which are 12vdc nominal, feed regulated 5vdc to the NodeMCU VIN pin. In addition, the power supply input (12vdc nominal) feeds source power to the voltage sensor. Sadly, while testing I used a small 9vdc battery as the power supply power source, and USB power plugged into the USB port so I could program the NodeMCU using the Arduino IDE. This worked fine for the most part. However, when I moved the project board to a true solar battery back (12vdc nominal) and then replugged in the USB power, so I could calibrate the sensors, the power supply burned out and destroyed the NodeMCU as well (I haven't checked the other sensors or OLED but they could be fried as well). The NodeMCU has a built in diode to prevent back feeding from USB power to the VIN pin, so I'm not exactly sure why this happened. The power supply voltage was at 14vdc at the time, but that shouldn't matter. In any case, the power supply fried and took the NodeMCU with it. NOT HAPPY...

Works, but adjusting screws very fragile
This product is fine, especially at the price. But be aware that the adjustment screw, which determines output voltage, is very flimsy, made of what appears to be thin stamped metal, and consequently is very fragile. I ruined one unit by using too much force on the screw; not too concerned about this given the price of the package.

Great Option
Everything exactly as described.We’ll made. Within spec.Recommended.

Very poor quality, don't buy.
Poor quality even for the Chinese... Had to fabricate a bit just to adjust the pot because it's such poor quality looking at it will break it. Then it turns a 8.4v into 7v or 1.6v nothing in between. Really bad.

Dc To Dc Step-Down
Product work as expected.

It works well
The pot screw is a little hinky but I like the size of it
