Is there a pin mapping of APM2, similar to the one available to APM1 (link: http://code.google.com/p/ardupilot-mega/wiki/Hardware)? Thank you in advance.
Looks like there isn't one, but the schematic is here: http://stuff.storediydrones.com/APM_v2_Eagle.zip . You can figure out the pin mapping from that... If I get a chance I might write up an update to http://code.google.com/p/ardupilot-mega/wiki/Hardware with the pin mapping and send it to someone with wiki commit access...
Isn't this what you're looking for: http://code.google.com/p/arducopter/wiki/APM2RC ?
