Properties:
【Ultrasonic module】: SUI04 is a transmit and receive hybrid ultrasonic sensor, it will help the drones achieve autonomous obstacle avoidance in 8 directions horizontal, obstacle avoidance to the top side and height keep to the down.
【High Accuracy】: Support 0.4 cm high detection accuracy, even the smallest obstacles can accurately grasp. Precise positioning without fear of obstacles.
【Small size and multifunction】: Single sample only 0.017Lb and 0.78 * 0.86 * 0.75in, easy to install on your drone. Obstacle avoidance function can be your device when the beginners practice flying.
【Compatible Mode】: It is suitable for Radiolink PIXHAWK and Mini PIX flight controller, and it also can automatically identify I2C, UART, MAV LINK port.
【Extreme reaction】: New upgrade of software and hardware, with dual filtering technology, 30ms quick response.
【Comprehensive obstacle avoidance】: 60deg larger angle beam angle, no blind zone for sending and receiving signals, only 6 planes can complete the obstacle avoiding the entire plane.
【Adapt to Multiple Use Scenarios】: Suitable for obstacle avoidance, drone teaching or drone selection for beginners in agriculture plant protection operations.

How to connect:
1. require your PIXHAWK is version 3.5 or later version, if you use automatic obstacle avoidance function.
2. Use the 6pin wire to connect the Ultrasonic Sensor SU04 insert to the TELEM1 or TELEM2 port of PIX.

Please note:
1. Automatic obstacle avoidance function asks the firmware from PIXHAWK's version 3.5 or later version.
2. The flight controller does not identify the detection distance, if the sensor is far from the obstacle more than 450cm, it will hold altitude by barometer.
3. PIXHAWK have to be powered by LiPo battery, it does not power through USB when you use this utrasonic sensor SUI-04.
4. When you are ready for the first flight, please make sure your drone is at a lower speed to keep the safe flight.
5. Please re-enter the PIXHAWK and re-open the MissinPlanner after all the parameter setup as all the above steps.
6. If you need to achieve the full obstacle avoidance effect, use a I2C expansion board or buy a Mini PIX flight controller with a factory-configured I2C expansion board.
