When I use LIDAR-Lite 3 Laser Rangefinder, I keep encountering the range finding value that the sequence window cannot output. The following file is the picture of my problem [problem] . How can solve the problem?

Hello @josh0222 and welcome to the RobotShop forum! I think this will help you out https://learn.sparkfun.com/tutorials/lidar-lite-v3-hookup-guide/troubleshooting Let us know how it goes :grinning:

I have replaced all the cables and electronic components. And simply using this program(see following website) to test lidarlite’s ranging function, it still presents the same problem. So I am wondering if it is possible that lidarlite is damaged? garmin/LIDARLite_Arduin…

Hi josh, Did you try adding the pull-up resistors and decoupling capacitor?

I connected it according to the lidarlite part of the wiring diagram below. It uses decoupling capacitors but no resistors. [接線圖]

You could try adding 4.7K external pullups to 5V for the SCL and SDA lines. Also, please check this topic [image] Lidar Lite v3 not communicating Robot Parts I have connected it both ways PWM and I2c and do not get any values either way. T…

I have a question. I use the 12C code and connection method. In the operation manual, the 12C connection method does not require an external resistor. It is PWM that requires an external resistor. In addition, I did not have additional resistors when I was operating, but it worke…

If the input voltage is only 4.5V, does lidarlite fail to work? Does the input voltage have to be 5V?

The I2C connection could benefit from pull up resistors, you can read more about this here: I2C at the Hardware Level - I2C - SparkFun Learn Each I2C bus consists of two signals: SDA and SCL. SDA (Serial Data) is the data signal and SCL (Serial Clock) is the clock si…

It should be said that I first use this code to achieve the scanning function (such as txt attachment). The first few times the operation was still very smooth, but after a certain operation, it started to encounter the problem of incorrect output. So I changed the cable first, a…

So I also have to confirm whether the current is operating at 135mA?

Also, please check this topic

If the Lidar Lite still does not work using an external power supply please create a support ticket with your order or invoice number and a link to this topic.
