Introduction

The LIDAR-Lite Series - the v3 and v3HP - are compact optical distance measurement sensors, which are ideal for drones and unmanned vehicles.

LIDAR is a combination of the words 'light' and 'RADAR.' Or, if you'd like, a backronym for 'LIght Detection and Ranging' or 'Laser Imaging, Detection, and Ranging.' At it's core, LIDAR works by shooting a laser at an object and then measuring the time it takes for that light to return to the sensor. With this, the distance to the object can be measured with fairly good accuracy.

By sweeping or spinning a LIDAR unit, systems can create detailed distance maps. Survey equipment, satellites, and aircraft can be equipped with complex LIDAR systems to create topographic maps of terrain and buildings. Luckily, Garmin™ has created a user-friendly LIDAR unit for your robotics and DIY needs!

Note that these use a Class 1 Laser, if you are concerned about your safety (in short: A Class 1 laser is safe under all conditions of normal use).

Hardware Overview

Differences Between v3 and v3HP

Functionally, the LIDAR-Lite v3 and LIDAR-Lite v3HP are quite similar. The primary differences are listed here:

Case

The LIDAR-Lite has two tubes on the front that contain a transmitter (laser) and receiver. You'll want to face these toward your target.

On the back, you'll find 4 mounting holes that are designed to accept #6 or M3.5 screws or bolts.

Wires

The LIDAR-Lite has 6 wires that can be used to communicate with the sensor.

Power

Both the LIDAR-Lite v3 as well as the LIDAR-Lite v3HP units require between 4.5V to 5.5V of DC power to operate (nominally, 5V). The LIDAR-LITE v3 can draw up to 135 mA of current during continuous operation (105 mA at idle). Contrarily, the v3HP unit draws up to 85 mA of current during continuous operation (65 mA at idle). To maintain a level voltage, Garmin recommends putting a 680 μF capacitor between power (5V) and ground (GND) as close to the LIDAR unit as possible.

Hardware Assembly

Follow the diagram below to connect the LIDAR unit to a RedBoard or other Arduino-compatible board. The LIDAR-Lite can communicate over I²C as well as use a pulse-width modulated (PWM) signal to denote measured distances. For this guide, we will show how to use I²C to communicate with the LIDAR unit.

Software

Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.

Garmin maintains an Arduino library to make working with the LIDAR-Lite very easy. Visit the GitHub repository, or click the button below to download the library.

Open a new Arduino sketch, and copy in the following code:

Upload the program, and open a Serial Monitor. You should see distance measurements (in cm) being printed.

Troubleshooting

Arduino Output Error

Are you seeing this output from the LIDAR-Lite V3 I²C example code with the decoupling capacitors connected to the Arduino?

You probably do not have a secure connection between the Lidar and the Arduino. I²C is sensitive to its connection. The cable wires are thin and can disconnect when in the Arduino's female header from a bump. A breadboard seems to work fine if there is not a lot of mechanical vibrations. However, a small bump can mess up the timing for the I²C even on the breadboard.

For a secure connection, it is recommended soldering header pins with some heat shrink or make sort of adapter when connecting it to an Arduino. Once disconnected, the Arduino might stop outputting sensor data. You can reset the Arduino for testing but to prevent the wires from disconnecting, it would be better to solder the wires to header pins. This is a common 'issue' with any I²C sensor and if they do not secure the wires, the Arduino will have problems talking with the Lidar Lite V3.

Decoupling Capacitor

Looking for a 680µF capacitor? Unfortunately, the SparkFun catalog does not include a 680µF capacitor. There are 1000µF capacitors, which can work as a substitute with the Lidar Lite.

Or, you can also wire capacitors in series and parallel to get an equivalent capacitance.

Dimensions

Product Showcase Example for LIDAR-Lite V3 Wand

Looking for the example code used in the product video for the LIDAR-LIte V3? Nick Poole basically used the same parts and example code that was used with the Lidar Lite V2 Glasses. For the Lidar Lite V3 Wand, he used the following components:

• LEDs
• micro-B USB Cable
• a backup portable cell phone charger

He happened to have a 5V/16 MHz Pro Micro around when building the project for the Lidar Lite V2 Glasses. The parts were reused for the Lidar Lite V3 Wand. Try looking at the old wishlist for the Lidar Lite V2 Glasses for more information. Make sure to also add a 1kΩ resistor when using the PWM wiring as stated on page 3 of the user manual.
