Lidar Lite back with V3 after Garmin aquisition

[Updated with more info] Glad to see that the Pulsed Light team, which joined Garmin earlier this year, are back with a new version of the Lidar Light range finder. Not many details yet, but it's now listed for $150 at Sparkfun:

  • Description: It’s back! This is the LIDAR-Lite v3, a compact, high-performance optical distance measurement sensor from Garmin™. When space and weight requirements are tight, the LIDAR-Lite v3 soars. The LIDAR-Lite v3 is the ideal solution for drone, robot or unmanned vehicle applications.

    This easy-to-use 40-meter laser-based optical ranging sensor has all the core features that made the LIDAR-Lite v2 so popular. Small in form and light in weight with low power consumption of less than 130mA during an acquisition. And it’s user-configurable so you can adjust between accuracy, operating range and measurement time.

    Each LIDAR-Lite v3 features an edge-emitting, 905nm (1.3 watts), single-stripe laser transmitter, 4m Radian x 2m Radian beam divergence, and an optical aperture of 12.5mm. The third 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 is user-configurable, allowing adjustment between accuracy, operating range and measurement time. It can be interfaced via I2C or PWM.

    Note: The LIDAR-Lite v3 is available for pre-order. We expect to have these in stock and shipping by early to mid-October. Adding a pre-order product to an order may cause a delay. Be sure to uncheck “ship complete order” in your cart to avoid delays in shipping in-stock items.

    Dimensions: 20 x 48 x 40 mm (0.8 x 1.9 x 1.6 inches)

    Features:

    • Range: 0-40m Laser Emitter
    • Accuracy: +/- 2.5cm at distances greater than 1m
    • Power: 4.75–5V DC; 6V Max
    • Current Consumption: 105ma idle; 130ma continuous
    • Rep Rate: 1–500Hz
    • Laser Wave Length/Peak Power: 905nm/1.3 watts
    • Beam Divergence: 4m Radian x 2m Radian
    • Optical Aperture: 12.5mm
    • Interface: I2C or PWM

Lidar lite is back with V3. When will 3DR be back with Pixhawk mini then?!

Although it doesn't list it as available yet, they say it will be soon.

I am very happy to see Garmin supporting this as a consumer / DIY product.

I am confused in the listing where they seem to describe both a laser and an LED version.

What is the one they are actually selling?

What are the performance (distance and repetition rate) specifications?

Hopefully more data will be added soon.

Best Regards,

Gary

@Johnatan: days...

Hi @Chris, what about Pixhawk2 ?

Comment by Johnatan on September 15, 2016 at 1:08pm

Pixhawk 2 (2.1 actually) will be out soon but not from 3DR. Check here for more info: http://www.proficnc.com/

It seems  a bit pricey. I was thinking to hack one of these 80m $32 units:

Will this unit still have the 13m issue?

There were more than just teh 13m issues. Lots of GPS jamming, the 13m issue, someones just dead on boot, not to mention the shotty i2c implementation. The Ardupilot devs tried to work with them but they just put the blame back on us every time.. even when we were able to duplicate it on their own example software and hardware. And this time they came out of left field with a new version, no devs involved with beta testing. More of the same from them, I don't expect it to be any better. I'll wait for V5 to come out

That's unfortunate, Still looking for a low cost reliable LIDAR unit that can range at least 40m for improving arduplane landings. Was hoping this could be it, even though it is a bit pricey.

Message from Customer service: Garmin and Pulsed light are currently working on a new and improve version of the Lidare Lite. The newer model, LIDAR-Lite v3, will be using a different chip for the signal processing and interface. This is mostly due to the many issues the previous chip had related to I2C bus handling and other less noticeable problems.
