Sorry, category says “Nano R4” but there’s not an option for the “Nano Connector Carrier”.
In the document at https://docs.arduino.cc/tutorials/nano-connector-carrier/getting-started-nano-connector-carrier/#qwiic-connector, in the Pin/Connection list it states that the VCC pin is connected to “+3.3 VDC/ +5 VDC (selected by the input selector switch)“. The schematic confirms that this is incorrect; the QWIIC connector, just like the SD card socket, are connected exclusively to +3.3 VDC, not to the switched power source. The I2C connection through the J6 Grove connector does use switched VCC, but the QWIIC connector does not.
