"For anyone elses notes, Pins 1 and 5 are 0V for the Radio port and 5V when USB is connected.  I confirmed that those levels are correct for my board and yet the data from the radio isn't making it on Radio.

"Thanks... I see that.  

The data still has to go through TS5A23157, and that is where I think my problem is.  It isn't switching from the data to travel through the telemetry port while the USB connection works fine.  SJ1 and SJ4 are hardwired to M…"

"Thanks for all the help.  I learned a few things today.


The hardware warranty from 3DR Robotics is only 90 days from date of purchase
That I am 90% sure that the failing part is the TS5A23157, so since they are only $1.10 each from Digikey, I thou…"

"Thanks, that is helpful.  Too bad the Eagle files are not available so I can understand some of the layers better.  

Sadly, unless I can fix this issue, the board is of no use to me if I can't communicated with it via RF.

I really appreciate your…"

"Hi Vishal

Your screenshots didn't make it for some reason.

My problem is that I am trying to figure out why I don't have Telemetry on the 3DR port when powered by the power module.  It isn't a radio configuration issue as I have actually had them…"

Would anyone know if there are Eagle files for the 2.6 board?I have an intermittent connection on the 3DR connector for some reason and I want to know if I can jumper over to the pads labeled UART2.Mike

"Hi Brandon

I ordered 5 of them.  If you want to send me your board, I can fix it if you are not comfortable doing it.  Zoltan at NGHobbies in Woodbridge (Toronto) can do it also.
From what I read, adding the cap on the +5v rail really helps too.

"Thanks

Let me share what I found.  It was a blown regulator that was shorted and outputting just under 5V.

The case on the APM is marked 2.6, but the board is etched as 2.5.4  to further add to the confusion that I was facing.

That 3.3V regulator…"

"And, ignore all the above.  The regulator is blown.  I guess I will have to get it a replacement.  "

Michael Walker replied to Michael Walker's discussion Bad Gyro Health
"I meant to add, this can't be a blown regulator as the gyro's work on an older version of the software if I roll back.
