VL53L1X-SATEL does not work on breadboard

I have VL53L1X-SATEL - Breakout board, I have successfully tested it on Arduino Uno/Mega using Sparkfun's Library (https://github.com/sparkfun/SparkFun_VL53L1X_Arduino_Library) . 

Now, when I connect the sensors's I2C lines on breadboard It doesn't work.

When I connect SCL and SDA of sensors to Controller's SCL & SDA respectively, It works perfectly.

What happens if I connect them breadboard and then to the controller? The reason I am doing this is I want to use two sensors so i have to connect them on breadboard and connect and SCL & SDA on same I2C bus.

    Hi,

    I'd like to work with VL53L1X-SATEL, but I can't find the documentation.

    Can you help me?

    Hi guys,

    VL53L1X-SATEL data brief with schematic can be found on st.com by searching VL53L1X-SATEL 

    To answer to k.kolhe1.5508372721541511E12's question: we do have two versions of satellite board for VL53L1X: blue color PCB version comes with the X-NUCLEO-53L1A1 pack can only be used with the expansion board X-NUCLEO-53L1A1 by connecting on the left or right satellite connector of the expansion board. The green PCB version sold in the VL53L1A1-SATEL pack can be used by connecting directly to a STM32 Nucleo board or to another microcontroller because on this satellite board there are voltage regulator, level shifter and pull up resistors SCL , SDA .... Which satellite version were you using?

    We do have the official version of the VL53L1X Arduino library here:https://github.com/stm32duino/VL53L1X. I connected two green satellite boards on the Nucleo F401RE without the X-NUCLEO-53L1A1 expansion board and it works perfectly.

    Thanks,

    Hi Julien,

    just a question: has the VL53L1X-SATEL  green PCB version distribuited with cover glass?

    Thanks a lot
