New APM2.6. Is one output fried?

Posted by Jon von Weymarn on September 21, 2013 at 1:48am

Hi all!

I updated from APM1 to APM2.6 and Output5 seems fried or something on my brand new board. I want to use the output for a camera gimbal and any servo I connect to this pin buzzes like crazy. All other outputs work as expected. I also tried different servos but the same behavior repeats.

Changes in Mission Planner don´t affect the results.

Here is a video of the behavior:

These are my MP settings:

    I bet you plugged the USB into the board with the rx inputs powered with 5v.  Death came quickly as the current would take out a track.  On mine it also took out a track to the 3.3v for the mp6000!

      Hi John,
      Sounds like a good theory as I remember at least once plugging in USB with RX connected. Anyhow, it works well on another output.

    I normally see people using pins 10 and 11 on the side rail for gimbal controls. Be careful powering your servos from the APM. You can cause a brownout. Best practice is to power servos with the seperate BEC. Also make sure to keep a common ground all the way round.
