Radiolink Autonomous Obstacle Avoidance SU04 & SUI04 Ultrasonic Sensor

Drone Ultrasonic module
SUI04 is a super mini ultrasonic module

for Drone, small body but excellent performance.
SUI04 is a new upgraded version of SU04. Single SUI-04 is increased from the original 30deg angle to 60deg beam angle obstacle avoidance.

Features:
【Ultrasonic module】: SUI04/SU04 is a transmitting and receiving hybrid ultrasonic sensor, it will helps the drones achieve autonomous obstacle avoidance in 6 directions horizontal, obstacle avoidance to the upward side and altitude hold to the downward.
【High Accuracy】: Support 0.4cm high detection accuracy, even the smallest obstacles can accurately capture. Precise positioning without fear of obstacles.
【Small Size and Multifunction】: Single probe only 0.017Lb and 0.78*0.86*0.75in, easy to install on your drone. Obstacle avoidance function can protect your device when the beginner practice fly
【Extreme reaction
】:New upgrade of software and hardware, using dual filtering technology, 30ms quickly response.
【Comprehensive Obstacle Avoidance
】:60 degree larger angle beam angle, no blind zone for transmitting and receiving signals, only 6 planes can complete the obstacle avoidance of the entire plane.
【Adapt to Multiple Usage Scenarios
】: Safety Guaranteed for Outdoors Operation and Training. Suitable for obstacle avoidance, drone teaching or drone selection for beginners in agricultural plant protection operations.

How to connect:
1.Require your PIXHAWK is version 3.5 or later version when you will use automatic obstacle avoidance function.
2.Use the 6pin wire connect the Ultrasonic Sensor SUI04 insert to the TELEM1 or TELEM2 port of PIX.
Please Note:
1.Automatic obstacle avoidance function asks the firmware of PIXHAWK is version 3.5 or later version.
2.The flight controller cannot identify the detection distance when the sensor is far from the obstacle more than 450cm, it will altitude hold by barometer.
3.PIXHAWK have to powered by LiPo battery, it cannot power by USB when you use this utrasonic sensor SUI-04.
4.When you ready for the first flight, please make your drone at a lower speed to keep the safe flight.
5.Please reconnect the PIXHAWK and reopen the MissinPlanner after all the parameters setup as all the above steps.
6.If you need to achieve the full obstacle avoidance effect, need to
buy an I2C expansion board or buy a Mini PIX flight controller with a factory-configured I2C expansion board.(SUI04)
