APM2.8 Flight Controller

APM2.8 Multicopter Flight Controller is an upgraded version of 2.5 2.6 with a Built-in Compass for FPV RC Drone Aircraft is the new APM2.8 flight controller. The sensors are exactly the same as the APM 2.6 flight controller, however, this has the option to use the built-in compass, or an external compass via a jumper. This makes the APM2.8 ideal for use with multi-copters and rovers.
The APM2.8 Multicopter Flight Controller is a complete open source autopilot system and the bestselling technology that won the prestigious Outback Challenge UAV competition. 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.
This revision of the board has an optional onboard compass, which is designed for vehicles (especially multi-copters 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 2.8 gives more flexibility in that positioning and is a good choice for them, too). This is designed to be used with the 3DR uBIox GPS with Compass so that the GPS/Compass unit can be mounted further from noise sources than APM itself.
