Had a reply from the Pulsed LIght, LLC.
In brief, LIDAR-Lite can operate from 0-40m with cm resolution. The overall accuracy is based on the reference clock which can either be internal to the programmable logic chip we use or an external source can be used. The internal reference is advertised by Lattice as having a 5% accuracy and we use that number in our preliminary specifications for the LIDAR-Lite product. Obviously, an external source would provide greater accuracy. In testing of our prototypes the accuracy using the internal reference has generally run better than 1% and we expect that would hold true in our production sensors. The rep rate is dynamically adjustable from 1-100Hz, although at the higher rep rates the range may be limited depending on the signal strength of the return signal.
Communications is via I2C at either 3.3 or 5 VDC logic and the bit rate is 100Khz. The unit operates as a slave and we are working on implementing user assignable addressing in the production sensors. Implementing this feature in the programmable logic device is a bit more complicated than we had anticipated, so it isn't in any of the prototypes at the moment.
I hope that I've addressed your questions. We do plan on having more information available online as we move toward production. If you have any additional questions, please feel free to contact me.
We are still testing the prototypes for real-world performance, which looks better than expected, so would only say that the specs may change as we release to production.
In addition to 3D Robotics writing code for their autopilot systems to support LIDAR-Lite, we also have a local Arduino group in Bend that is working on code for the Arduino micro controllers and will make that available along with other operating information as it is completed.
Please note that the information above is subject to change as it is a product in progress. Nevertheless it looks very promising!
If I get more information I will post it here.
