### Board Selection

The Nano Connector Carrier lets you select +5 VDC or +3.3 VDC Nano boards to ensure compatibility with the whole Nano family. To do this, toggle the carrier onboard switch to its respective position, following the table below.

### Qwiic I2C Connector

The Qwiic connector is connected to the standard I2C bus on the board (via A4 and A5 pins). It is powered via +3.3 VDC, following the Qwiic standard system, making the Nano Connector Carrier compatible with the Arduino Modulino nodes.

Its logic level is fixed to +3.3 VDC, which is translated to the host Nano board voltage defined by the board selector switch.
