Tips

\_x000D\_

\_x000D\_\* CAN Baro is enabled by default, If you don’t use the Baro integrated in AUAV, set “BARO\_ENABLE = 0” in “Mission Planner->Initial Setup->Optional Hardware->UAVCAN->MAVlink CANx -> Menu Parameters” \_x000D\_\* ArduPilot has removed AUAV I2C support by default on flight controller with 1MB flash MCU(such as F405, F745 series). \_x000D\_ \_x000D\_ \_x000D\_

AUAV vs DLVR

\_x000D\_\* Speed range 400km/h vs 227km/h \_x000D\_\* AUAV has better offset in still air. \_x000D\_ \_x000D\_
