(2) IMU (Inertial Measurement Unit):
Built-in inertial sensors, for the measurement of aircraft attitude; built-in pressure sensor for the detection of
aircraft altitude. Should be connected to the CAN1 port of the Controller Unit, and be mounted according to
the required location and orientation. The IMU has been calibrated before delivery, it should be used under the
specified temperature; otherwise the temperature may have an effect on the IMU performance.

Orientation Requirements:
Please mount the IMU as one of the following options. Configure in the A2 Assistant software ->Basic ->Mount ->
IMU, and select the matched option.
Pointing Forward
Pointing Backward
Pointing to Left
Pointing to Right
Location Requirements:
Center of
Gravity
Fix with
double faced
adhesive tape.
(1)
The top side should be facing up. DO NOT mount upside-down.
(2)
DO NOT cover the ventilation holes, keep them unblocked and clean.
(3)
Take heat preservation measures if working in cold weather.
(1)
Mount the IMU at a low vibration position and the sides of the IMU should be precisely parallel
to the aircraft body. Based on our experience, there is less vibration near the aircraft’s center
of gravity.
(2)
NOT water-proof or oil-proof.
(3)
Check the double faced adhesive tape regularly to make sure that the IMU is fixed firmly.
There is a CAN-Bus connector, which can be used to connect to the GPS-COMPASS PRO or other DJI product.
