Note: 

• ESP header: the ESP32-S3 module on this board operates on 3.3 V. The ESP header located close to the USB-C® connector is 3.3V only and should not be connected to 5 V. This may damage your board.
• Qwiic connector: the Qwiic connector on this board is connected to a secondary I2C bus on this board, IIC0. This connector is 3.3 V only, connecting higher voltages may damage your board. To initialize this bus, use Wire1.begin() instead.
• Maximum current draw per pin: the UNO R4 series’ maximum current draw per GPIO is 8 mA, which is significantly lower than previous versions. Exceeding this limit may damage your pin / board.
