APM (Ardupilot Mega) is an open-source autopilot system. The bard can convert any fixed-wing, rotary-wing, and multi-rotor vehicle (even boards and car) into a completely autonomous vehicle, capable of performing a task like programmed GPS missions with waypoints (with the optional GPS module).
APM2.8 is an updated version of 2.6 with a built-in compass. The module includes a 3-axis gyro, accelerometer, and high-performance barometer. However, sensors are exactly the same as APM2.6 but with an extra option to use between a built-in compass or external via jumper.
It allows users to interface via various interfaces for programing, reviewing logs, even some apps for smartphones and tablets. The optional MAVlink telemetry radio allows two ways of communication that give you full control and provide live data back to the user’s computers, tablets, or smartphones. The list of what this flight controller is capable of has quickly been suppressed with what it can not do, with features flight modes and supported platforms.
The revision of the board has compass onboard compass, which is designed for the vehicle (especially for multirotor or rovers) where the compass should be placed as far from power source and motors as possible to avoid magnetic interference.
