Product Review

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 (see option below), so that the GPS/Compass unit can be mounted further from noise sources than APM itself.

Features:
Controller board:
- Arduino Compatible
- With top pin conectors.
- Includes 3-axis gyro, accelerometer and magnetometer, along with a high-performance barometer
