Qwiic Proximity Sensor (VCNL4040) Hookup Guide
With the Qwiic connector system, assembling the hardware is simple. All you need to do is connect your Qwiic Proximity Senor to the RedBoard Qwiic with a Qwiic cable. Otherwise, you can use the I2C pins, if you don't have a Qwiic connector on your microcontroller board. Just be aware of your input voltage and any logic level shifting you may need to do.
