    Can the VCNL4040 be daisy chained so I can have say 5 of them in my project and only look for a reading on the active sensor?

    • It cannot as it only has one I2C address (0x60) I'd suggest using our Qwiic Mux

        Thanks for the quick reply. Thats discouraging, I was hoping to save on cables coming back to the main board.

          Hi there, it sounds like you are looking for technical assistance. Please use the link in the banner above, to get started with posting a topic in our forums. Our technical support team will do their best to assist you.

          As a note, as described in the I2C tutorial and the Qwiic Mux hookup guide, you will find that you will still only need the Qwiic connection (aka the 4-wires) coming back to the microcontroller.
