Can alternatively serve as SBus out but not yet implemented. In many situations this is not bad: for instance: when testing the AHRS attached to your computer: it can not accelerate for a very long time (at most a few meters: so if you accelerate to the left, then you need to accelerate to the right directly after so the average is zero) and can not rotate to much either (or your cable gets strangled). I opted for that, initially, since it will likely be prone to wheels spinning etc so encoders on the wheels would not help as they would generate errors where the wheels turned but the chassis stayed put. The key difference between an inertial measurement unit (IMU) and an AHRS is the addition of an on-board processing system in an AHRS which provides solved attitude and heading solutions versus an IMU which just delivers sensor data to an additional device that solves the attitude solution. townofmtmorriswi.
