    Perfect to connect the DJI AirUnit if you don't have 9V from the FC

    It turns out that the absent trimpot (the "adj" jumper bridge option) has been replaced with a 39KR, exactly the same value connected to the 5v option link which makes it preset to 5v without the need to solder blob any of the voltage option links. I found this out the hard way two days ago when I'd finally gotten round to using it in my DIY GPSDO project. If you remove this "excess baggage", solder blobbing the relevant voltage option links will now produce the indicated voltages. I also discovered, after turfing out the redundent 39KR from the trimpot location (it already has one in the 5v location!), you could combine the 9 and 12 options to get within a tenth of a volt of the 5v setting which might prove handy if this works out a little higher than the 5v link gives - I was getting 5.05v using the 5v link (or leaving them all open with the surplus resistor still in place) and, just 15mV more using the 9 and 12 volt links together instead - not quite a good enough improvement, I was looking to get 5.15 to 5.25 volts so used a 1K5R smd resistor to bridge the 5v link which got me a voltage of 5.216 open circuit and 5.17 on a 1A test load. Obviously, you can use variations on this idea to fine tune the voltage setting. Unfortunately, I managed to burn out the very tiny converter IC with the slip of a DMM probe so I'm now back to the other converter module I'd bought at the same time from BG way back last August :-( It's so sad because that was a really crap version of the one I thought I'd be getting going from the product pictured. The one, as pictured is probably ok but the one I got (not this module, I hasten to add) was so bad, I have to regard it as a "Fake version" in need of some remedial attention to get it to function properly (the Shottky diode was left disconnected from the inductor - a solder bridge needed to be closed and the crappy trimpot had to be slung in favour of a fixed value 33KR resistor to avoid the over-volting risk it had represented).

    While the device worked for me giving the required 5v output, the solder links on the back did not appear to work as labelled. Putting a bridge across the 5v gave me 2.7v No bridge gave me 5v Possibly an incorrect resistor installed

    As others have mentioned, the diodes are all mixed up. In fact there is no bridging you can do to get 3.3v at all. However, I am able to get 3.55v and my project requires a 2.7KOhm resistor on the output. With that in place, I can get 3.2v. Hopefully that will work..

    As other pointed out the bridges are not coding proper voltage values on output. 3.3 -> 2.6 v, 12->3.7V Probably there is improper resistor soldered in the feedback divider. A fail.

    it is small well working step-down, but if you want adjustable V, you need to add trimmer
