VL53L4CD

Hi there,

I'm planning to integrate the VL53L4CD sensor into my custom board, which features the STM32G484CEU6 MCU.

After reviewing the datasheet, I found that the sensor operates within a voltage range of 2.6-3.5V (nom 2.8V). I just wanted to double-check if it's safe to connect this sensor directly to the MCU, considering that the I2C interface of the MCU is 3.3V.

Thank

Welcome @hbagheri, to the community!

Now, since 3.3V is in the range of 2.6V...3.5V, you can also supply the sensor from the 3.3V of the board and connect it directly via I2C.

Does it answer your question?

Regards
/Peter

    I have a quicker answer - YES. 3v3 is just fine. Do try not to over-voltage it though. Cuts down on the lifetime. 

    But 3v3 is well tested and will work for you.
