NEW APM 2.5 Pin out and Wire Diagram And Camera Gimble explanation
Hey guys i recently got the APM 2.5, when looking at the pins, I saw A0 - A11 Pins werent being used and i did not know what they were for so i was googling and found a PDF that stated

A0- Sonar/ Ultrasonic A1- Voltage Sensor – Attopilot
A2-Current Sensor – Attopilot
A3- Optical Flow Sensor
A4-Motor LED
A5-Motor LED / Buzzer
A6-Motor LED
A7-Motor LED
A8-Motor LED / Analogue RSSI
A9-Camera Shutter
A10-Camera Roll

Link to Gimble explanation in google

So After researching for some time, I have found that for a camera gimble A10 is roll and A11 is pich but there was no explanation of were Pan is connected (YAW).So I i dug some more and found some consensus to the following :
Currently Mission Planner shows that we have 3 axis so would be good to update that. I suspect (haven't check the code) that PAN goes to A9 but that is just a guess.
Anyway, I lack one wiki page on those extra outputs, what can be connected to them. So we have A11, A10 (and A9?) for gimbal, A1 and A2 for AttoPilot? current/voltage sensor:.

So after my post was denied several times as being " a request for assistance" let me rephrase, What is your guys experience, have you tried A9  and it worked or not, what other solutions have you tried?

Here is more info:

Good Documentation.  Tnx for sharing

There is certainly a need for more explanation for these pins

Not sure what "motor LED" means for instance

Lots of potential but don't know how to tap it

Thanks for the post

MIne not function for the camera Roll and Pitch  gimble function on any Pin

you enabled the gimble in the missionplanner?

A9 is PWM out you can use it for anything that needs PWM out. You can configure in mission planner or advanced parameters page

If you got the plastic case, dont trust in the numbers printed on this because they dont match with the pins.

jared: the diagram is labeling the SPI port as A9-A11, which is wrong. Also note A9-11 can either be PWM out 9-11 or analog in see to see how they can be changed

In mission planner you can set the battery voltage and current to pins A0-A13. Where is A12 and A13 ?


Comment by Bill Bonney on May 19, 2013 at 8:45am
@earl: A12 & A13 are routed to the Power Management port for the power module.

@stone1295: Mike A12 is not under the S+- in the diagram. That's the SPI port.
