VL53L4CD In this sensor how to use it stm32G071RBt6 controller, maximum how many device can connect?

Hello,

To connect VL53L4CD with any MCU you need I2C interface. No matter the MCU used (nothing to do with STM32)

And this depends on if you need to connect all of them on the same I2C bus or separated I2C instances (stm32G071RBt6  has two I2C instances: you need to check the product datasheet)

Technical points to address: bus addressing (7-bit, 10-bit), bus capacitance etc ..
