I am having difficulty with the APM 2.5 board that I just received. I can't seem to make sense of the older APM 2.0 board.

Here is the board that I have:

What I am trying to understand is where to connect the following:

PDB

Xbee

Do I connect the PDB to the green and blue?

Do I connect the Xbee to the URART0?

You need to be a member of diydrones to add comments!

apm25, pdb, uart0

The front of the APM 2.0 is different from the APM 2.5. The APM2.5 has a white 5 wire connector while the APM2.0 has std pins.

Here is the front of my board:

I also read other posts by Vernon Barry that the UART0/2 does not work even after soldering the automux. Am I supposed to solder the automux and am I supposed to put a white 4 pin connector on the wires coming out of the xbee shield?

So that is my point, I just want some good instructions. Is this something that someone from DIYDrones can update for us?

Just received mine and the Uart0 in the location upper right is prefered but there is a different conector that I have not yet identified. In the mean time attaching the Telm. to the optional Uart0 were you have it identified in red works fine.

I would connect the Xbee to the UART0/2 that is in the top right of your image. That matches the instructions where telemetry is hooked up.
