This is the LIDAR-Lite v2, a compact high performance optical distance measurement sensor from PulsedLight. The LIDAR-Lite “Blue Label” is ideal when used in drone, robot, or unmanned vehicle situations where you need a reliable and powerful proximity sensor but don’t possess a lot of space. All you need to communicate with this sensor is a standard I2C or PWM interface. With everything connected the LIDAR-Lite v2, with its range of up to 40 meters, will be yours to command!
Each LIDAR-Lite v2 features an edge emitting, 905nm (75um, 1 watt, 4 mrad, 14mm optic), single stripe laser transmitter and a surface mount PIN, 3° FOV with 14mm optics receiver. The second version of the LIDAR-Lite still operates at 5V DC with a current consumption rate of <100mA at continuous operation. On top of everything else, the LIDAR-Lite has an acquisition time of only 0.02 seconds or less and can be interfaced via I2C or PWM.
The LIDAR-Lite v2 has received a number of upgrades from the previous version. With the implementation of a new signal processing architecture, LIDAR-Lite v2 can operate at measurement speeds of up to 500 readings per second offering greater resolution for scanning applications. Additionally, the LIDAR-Lite v2 has had its I2C communications improved to operate at 100 kbits/s or 400 kbits/s with you, the user, able to assign your own addressing! Just in case you are wondering: yes, the LIDAR-Lite v2 is compatible with its previous version in all primary functions and their compatibility will extend into the next version and beyond.
Note: With Garmin® recently acquiring PulsedLight® the LIDAR-Lite v2 has been marked EOL. We are currently waiting on word about the next exciting product these two companies create. We will come back with additional information once we obtain it.
Note: The LIDAR Lite is designated as Class 1 during all procedures of operation, however operating the sensor without its optics or housing or making modifications to the housing can result in direct exposure to laser radiation and the risk of permanent eye damage. Direct eye contact should be avoided and under no circumstances should you ever stare straight into the emitter.
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.

easy plug and play thank to library and github. However, power comsumption is around 120mA. Thus, I recommend to power the module separately from a 5V external supply (7805 regulator for example) : Indeed; if you use a Arduino board (even with the 680uF capacitor on 5V pin), you may have some trouble as the arduino 5V pin is not able to deliver more than 100mA. Once done, The lidar works perfectly. Philippe

I used the PWM integration option with my Pixhawk controller and it’s working flawlessly. Altitude hold mode is now solid as a rock. Very nice.

Albeit a smoothing capacitor, it’s just 2 wires for I2C and 2 more for power. I immediately hooked it up to a Mega, #included <Wire.h>, and received amazeballz resolution and accuracy. Hooked up a buzzer and made a super accurate theramin, I also left it pointing at the road overnight to count cars and it never failed or got hot. Definitely a great module for any accurate or quick ranging requirements.
FYI: In Pulsed-Light diagrams they use an electrolytic capacitor between 5v-Gnd, this is a decoupling or bypass capacitor that’s meant to smooth-out the power coming into the LIDAR module. It is not required, but it is recommended since it stabilizes operation and readings by offering a consistent voltage for the device to work off of.

Library is simple, with great instructions, but there’s a ton of noise in this version (even the library says it’s “virtually required” for this version) if you don’t have the capacitor. Sparkfun doesn’t sell the required cap (and doesn’t ship with it), so now i’m off ordering a set from mouser + shipping.
It’s simple to use, but I hope the cap stabilizes the data. I’ll post an update after I find out.
The Lidat Lite was a great produuct. It worked flawlessly, and it did what is was supposed to do. I have made a radar on my youtube channel, the name is Jyo Pari if you want to see it.
I tried it on an Arduino Uno with examples found on Github, worked great. I also worked on getting it working on the Intel Edison where i ended up writing my own code for. I posted the code on Github if anyone else is interested. https://github.com/aafeliz/LIDAR-Lite-v2-edison.git

It is part of a large for college to map a room and we haven’t really messed with it yet.
Now I’m waiting for the manufacturer to post more detailed information about how to best utilize the new features.

Bob Evermore of PulsedLight, Inc told me they are only supporting Arduino, so you are on your own if you want to use it for Windows 10 IOT or anything else…
