APM2.6 Specifications:Compare with APM 2.52: APM 2.6 without welding electronic compass on the mainboard, the board has no onboard compass.
System: complete open source autopilot system
APM2.6 Features:
1. It allows the user to turn any fixed, rotary wing or multirotor vehicle (even cars and boats)into a fully autonomous vehicle; capable of performing programmed GPS missions with waypoints.
2. 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. (On fixed wing aircraft it's often easier to mount APM far enough away from the motors and ESCs to avoid magnetic interference, so this is not as critical, but APM 2.6 gives more flexibility in that positioning and is a good choice for them,too). This is designed to be used with the 3DR uBlox GPS with Compass , so that the GPS/Compass unit can be mounted further from noise sources than APM itself.
3. APM 2.6 requires a GPS unit and external compass for full autonomy. Choose your compass from options menu at right.
