APM 2.5 pinout

So I messed my FMU on my APM and no longer will use it as a flight controller.

I im going to end up using the APM for arduino projects im working on. Does anyone have an easy to read pinout for the AT2560 to APM layout?

I know of this schematic but im looking for something that I can lookup a bit faster.

  • Just use any of the serials, TX/RX/GND is all you need to play with it on arduinos [I prefer teensy boards as they have hardware serials] But using a serial will allow you to do most everything you need via mavlink.
