This revision of the board has no onboard compass, which is designed for vehicles (especially multicopters and rovers) where the compass should be placed as far from power and motor sources as possible to avoid magnetic interference. APM 2.6 is designed to be used with the 3DR uBlox GPS with Compass (see option below), so that the GPS/Compass unit can be mounted further from noise sources.
APM 2.6 requires a GPS unit with an onboard compass or an external compass module for full autonomy. If you are using APM 2.6 with a GPS module that does not have a compass sensor, you must use a stand-alone external compass. We recommend this one with this cable.
Note: APM 2.6 is compatible with APM:Copter 3.2 and earlier only. To use APM:Copter version 3.3 and later, please purchase a Pixhawk. APM:Plane and APM:Rover offer full support for APM 2.6 in all existing releases.
