Ordered 5 got 7 :-) Thank you very much for the premature Christmas gift!
The only thing, I have to criticize is that both outputs are labeled "OUT -" (see picture)Comments (1)Show Original -

vjgeor VIP2GR24/12/2020Works amazingly for such a small thing. It is so small, it is difficult to solder wires and you need a 1mm screwdriver to adjust. However, once adjusted it has very good input regulation ( see images). From 8.90 to 14.50V input the output changes only 1mV! The input must be at least 1.5V above the desired output for it to work. Adjusting to 3.3V is very touchy if you try to hit 3.30V exactly. I have not tested it for loads regulation or at high current yet.

0A:These modules are not meant for such a high current draw that you are describing. Just like watageek suggests these modules are for powering things like flight controllers or general peripherals not ESC's or motors.Answered by Gaz on 27/11/2018Helpful (0)
-
0A:Yes. This should be just the thing. Also, if you trim this carefully for 5 or 3v3, you can pass or remove the on board regulator and use this directly for the controller, which will be more efficient than chaining the two. But just connecting this to the 9V input (after you trim the output voltage to 9V!) would probably give smoother voltage.Answered by realblades on 03/08/2019Helpful (0)

0A:The holes (1mm) are for connecting input and output, so only 2 are grounded. I don't think there are premade mounting solutions which take this into account.Answered by BG741413216 on 15/03/2023Helpful (0)

0A:You can adjust with the small trimmer: any output voltage between 0 and about 1.5 V below the input voltage.Answered by MihaiP on 13/12/2020Helpful (0)

0A:maybe you can try.Answered by Ambrosial on 01/06/2020Helpful (0)

0Q: Keep it the output voltage stable also if the source-voltage changes (like energy from solar cells)?A:As long as the input voltage is greater than the set output voltage.Answered by BG741413216 on 15/03/2023Helpful (0)
