LIDAR has never looked so good! This is the LIDAR-Lite v3HP, a compact, high-performance optical distance measurement sensor from Garmin™. The LIDAR-Lite v3HP is the ideal optical ranging solution for drone, robot, or unmanned vehicle applications. Each sensor is housed in a durable, IPX7-rated housing and includes all the core features and user configurability of the popular LIDAR-Lite v3.
The v3HP is very similar in function to that of the v3 but it can now sample faster at rates greater than 1kHz (where as the v3 is only capable of up to 500Hz). Another improvement is that this v3HP model is more power efficient with current consumption rates 40mA less than the v3 (that's 65mA as opposed to 105mA while idle, and 85mA instead of 130mA while acquiring).
Each LIDAR-Lite v3HP has a range of 1m to 40m and features an edge-emitting, 905nm (1.3 watts), single-stripe laser transmitter, 8m Radian beam divergence, and an optical aperture of 12.5mm. This version of the LIDAR-Lite still operates at 5VDC (6V max) with a peak power of 1.3W and still possesses an accuracy of +/- 2.5cm at >2m. On top of everything else, the LIDAR-Lite is user-configurable, allowing adjustment between accuracy, operating range and measurement time and can be interfaced via I2C or PWM with the attached 200mm cable.

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

The device is worth choosing over the former model just for the double sample rate alone. Good construction. Water resistance is a nice touch, but only as a safety measure. Optics will not perform if you get water onto the lenses and if you plan on exposing the sensor to moisture, I recommend enclosing it in glass or non-IR-blocking plastic, or at the very least covering the front. Leaving lenses exposed is always a bad idea when dealing with precision instruments.
The only thing missing that would make it a perfect point cloud scanner is an RGB sensor. I'm having to combine mine with a standalone module and alignment is always an issue, but for the price that low, can't complain. Love this thing!
Getting two of them to work on one I2C bus was a little tricky, but I'm very impressed with the accuracy, sampling rate and the relative ease of setup.
For the price, I'd be hard put to do better.
I am using the v3HP as a robot range finder and it works great. Very robust, works in sunlight.
