VOXL Flight IMU Hardare Configuration
VOXL Flight has two IMUs connected to the snapdragon and three connected to the PX4 flight controller MCU.
In the VOXL-SDK, both snadragon IMUs are enabled and provide data through MPA, however IMU0 should be preferentially used since it is a newer and better performing part. Note this differs from the VOXL board which contains two of the same IMU. Configuring MPA services with voxl-configure-mpa will select the correct IMU based on board part number.
