## Description

desertcart.com: Radiolink SU04 Ultrasonic Sensor Range Finder Obstacle Avoidance for Helicopter, Multirotor, Airplane, Car, and Boat, Compatible with PIXHAWK, Radiolink Mini PIX and crossflight : Industrial & Scientific

Review: Product As Described & Excellent Customer Service - I have this connected to Radiolink's PX4 Mini and using it in a Plane for Landing and Approach. Had issues with Bad Lidar Health and the customer server representative escalated this issue immediately to their technical department. After a few emails back and forth they provide a firmware update to address the issue. This is awesome especially if you have ever worked with Pixhawk or APM etc.... Good job
Review: Configuration - I am giving a three star since while I finally got it work, this should not be so difficult to configure... Here is the parameters that worked for me on a pixhawk 2.4.8: RNGFND1_TYPE:2 RNGFND1_ADDR: 112 (0x70) I had to run i2c_scanner on an arduino to get the I2C address... This address DID NOT change when I press the button (contradicting the answer from the seller)! But I got it to work now. The performance is as in the spec (min:0.47m, not sure about max yet). The vendor show provide more accurate information on how to configure it.

### ⭐⭐⭐ Quality is hit or miss but not a bad buy.
*by A***R on January 5, 2020*

I have had 2 years of these that were poor quality. One arrived with the cover unattached. One arrived with a poor solder on the button and wouldn’t power on. I still have several more and they do seem to work if you get a good one. I have these on a pixhawk S500 frame and on a Minipix that I put on a eachine wizard 220s-hv frame just for fun.
