Title: no longer have the 3.3 voltage reducer on my cc3d for connecting the satellite
Post by: Que on March 03, 2017, 09:26:53 pm

Anyway to make this work without wiring in a voltage reducer? I lost the use of the soldering pad in a crash

You can find the 3.3V in various places, like around the regulator. (blue dots)

 Are the blue dots my soldering points?
Also I'm using an xt60 pdb...I can run power to the cc3d from the 5v pads right?

yes, just after you test with a voltmeter.

Well my 5v pad is no longer reading at 5v

I don't think I can solder to those tiny little points...I'm good but not that good

Assuming the 3 blue dots refers to the same PCB trace your can solder without issue.
