@@AlbertKimTV Another (hopefully not) silly question: the ground that goes into the regulator looks like it's soldered to a spot next to the ground from battery. Looked at F3, not sure what it is. Can I solder to the actual ground instead, like the VCC?
@AlbertKimTV5 жыл бұрын
Ground is the same everywhere. You can solder to any ground you feel like.

Hi Albert, I tried this for my crazybee F4 pro v2, running 2s battery with 5v regulation, flying very well but why is my board so hot? I don't have a temperature gauge, it's above 75 degrees Celsius :(

Question! I’m already using that 5v out pad to power a rx. Can I bee(haha) feeding voltage to that pad while still powering the rx with it??? I’m guessing no but I’d love to hear the opposite
@AlbertKimTV5 жыл бұрын
Yes, that's OK. In and out on the same pad is not a problem as long as the voltage range is correct.

how about replacing the dead regulator IC on the board? :)
@AlbertKimTV5 жыл бұрын
I think definitely possible but that part is harder to find. Do you know where to get one?
@cahePL5 жыл бұрын
On mine the IC is B6287S, very widely available chip. Probably it's something else on the 2S capable boards, since this is only used to boost 1S to 5V.

So that's kind of good.. Question is why are they not fixing the problem?
@AlbertKimTV5 жыл бұрын
The regulator was probably meant to only power the AIO camera with low current draw. Now a lot of people are modding and adding bigger cameras and VTX, etc... so the regulators are getting pushed beyond what it was intended for.

all the 5v connections are the same anywhere. Basic electronics knowledge here.
