2pcs VL53L0X Time-of-Flight Flight Distance Measurement Sensor Breakout VL53L0X ToF Laser Range Finder for Arduino (Black)

As far as the piece that did work, it's running fine and very accurate. Just unfortunate that the 2nd piece was broken. Could connect to it and load firmware on it, but just wasn't reporting any distance info.

The media could not be loaded. These worked much better than the ultra-sonic sensors I first tried. The beam cone is much tighter with the VL53L0X. I used two of them attached to arms mounted to the front of the robot. The idea was to drive the robot manually and as soon as the pole is sensed, the robot goes autonomous, self aligns to the pole then drops the cone.Each VL53L0X measures the distance to the pole and when left == right, drop the cone. The reason I use two sensors is that the distance to the pole will change depending on if there is no cone or multiple cones already stacked on the pole, or if different cone sizes are used.These VL53L0X's worked well but I knocked one star off only because there was noticeable sensor to sensor variation. It was consistent though, so it was easily fixed by adding an offset in the code to match them.

I bought two of these items at the end of the year, and unfortunately was unable to test them right away, so they cannot be returned now. Anyway, one of the devices will work sort of OK with about 30% error after 40cm. The other device reads between 78mm and 110mm only. This is in a dark room with a white target.My recommendation is if you buy them, test ALL of them ASAP.

Ok but only 1 out of the 2 worked.
