Not Recognizing the Lidar Lite 3 attached to Raspberry Pi

When I use the utility " i2cdetect -y 1" nothing is detected. I have no reason to believe the utility is not working. It brings up an entirely empty array.

I have taken a picture and this is the dropbox link dropbox.com/s/vkp0nwu7h0nye … d.jpg?dl=0

To summarize I have connected the Pi’s (B+ version) 5volt pin (2) to the + breadboard and the Pi’s ground pin(6) to the negative. The 680 uf capacitor is in between the Lidar Lite’s power and ground to the breadboard. I also directly attached the Lidar Lite’s clock and data line to their respective counterpart on the PI - pins 28 and 27.

At this point I am simply out of ideas and would appreciate your indulgence.

Hi,

It is quite possible that the power provided by the 5 V DC pin of the Raspberry Pi is simply not enough. As mentioned here, the LIDAR-Lite can require up-to 500 mA during initialization. If the proper amount of current is not provided, it may simply not initialize properly (and therefore not provide any data when polled by the Raspberry Pi).

You may want to try the LIDAR-Lite again with your RPi by using a separate, stable 5 V DC power source for the sensor.

Sincerely,
