Hi Folks - a quick heads up to anyone else who may be using these rather nice Ubecs from Holybro, I have just had a fault that I found was caused by having 9.2V on my Ubec output rather than the 6v I thought I had set - upon investigation the little DIP switch on the Ubec PCB is soldered on upside down and therefore ‘On is OFF and Off is ON’.
Holybro are aware but there may well be many more out in the field like this - you can tell if your Ubec is faulty by looking at the DIP switch through the case, the DIP switch ‘ON KE’ mark should be AWAY from the PCB edge - opposite the ON of the silk screen of the outer case.
You could open yours up and resolder the switch if you have the skills, or mark up the ON and OFF Silk screen on the case the other way - whichever way I shall always test a Ubec with a meter before going live in the future!
