Good day, you must follow the correct pinout for i2c… gnd-sda-scl - 5v.
I suggest you to power the rangefinder with an external power source… like an ubec.
for the pinout follow this
My name is Mohit from LightWare Lidar, I can assist you with getting your unit up and running.
Please download LightWare Studio from :
Please install and open the software once opened.
Plug in your SF11/C to your computer using the USB cable.
Select the device that appears and navigate to the parameters tab.
Ensure the following parameters are set :
I2C addres: 102 / 0x66(Hex)
I2C Pixhawk compatibility mode is switched on.
Please unplug your device and connect your device to your Pixhawk ensuring that your cables are as follows:
The SF11/C should be connected to the Pixhawk I2C connector as follows:
Red (SF11) -> Pin 1 on Pixhawk (5V)
Green (SF11) -> Pin 2 on Pixhawk (SCL)
White (SF11) -> Pin 3 on Pixhawk (SDA)
Black (SF11) -> Pin 4 on Pixhawk (GND)
Hi @Ronl5555, a word of recommendation, connect the 5v to a BEC if possible. Personally my pc didn’t provide enough power when connected to the FC when the range finder was connected and all you can hear when it happens is the buzzer clicking.

1.The range of the meter is 120m during daytime.
2. Please note that water is a dynamic substance. It could be subject to many conditions, such as calm water, waves, highly reflective, or murky.That said we have configured the SF11/C to fly over water. one of the applications being whale watching. We have an FAQ on how to setup the SF11/C to fly over water, I will link it below.
3. Our products are used for agricultural purposes and can be configured for this application too. I would be more than willing to assist you set up your device for this application.
Hi @Mohit_Morar
I was wondering if setting the sf11/c to the aforementioned settings for getting good results over water surface as default would seriously hurt results over ground surfaces? Since I do both in the same flight for video purposes
Thank you
Effectively using the above mentioned settings will not impact your readings over ground surfaces. It may assist you if you are getting lost signals or false returns to omit them by applying this filter. As long as the unit receives positive readings the device reports them as normal. it just filters out lost returns.
