So i finally have a new regulator installed and the board has come up on mission planner motors arm no more bad gyro health displayed in the data page but now i don't have any GPS it was working just fine what could be causing this to occur thanks for any help.

Hi guys,

Any advice on what gimbal model will allow me to use two cameras simultaneously? I am not sure if such a gimbal exists? Additionally, would it be possible to remotely trigger two cameras at the same time? Thanks

the voltage is 4.3 v and my flight data page was not going crazy as most have described only the bad gyro health so wait and see i guess.

Good deal.  Just out of curiosity, what voltage did you measure?

Comment by Dennis Fuente on January 8, 2014 at 2:16pm

I have checked the voltage at the regulator and it is above 3.3 v so i have ordered a replacement for it my hope is that nothing else has gone down.

Thanks for the help

@Dennis,

This regulator is being used to take the 5V board input and regulate it down to 3.3V.  When a regulator fails, it could fail multiple ways, no output (Hi-Z), output grounded, or output shorted to input, for example.  This one in particular seems to favor failing with the output (normally 3.3V) shorted to the input (5V).  You will need to perform the check documented in the video on the page that I linked to confirm if this is indeed the issue that you are observing.  It's a pretty simple test if you have a basic multimeter.  If that's the issue, replacing the regulator should get you back up and running.
