1. Pin changes: Two I2C pins are added next to the AREF pin (SDA and SCL are just copies of Analog 4 and 5, not an additional I2C interface), and two pins are added next to RESET, one is IOREF The expansion board can be adapted to the onboard voltage.
2. More stable RESET circuit. The position of the RESET button has also changed, moved to the corner of the board near the USB interface, making it easier to press.
3. ATmega16U2 replaces 8U2. This does not mean that R3 with 16K flash memory can make your code run faster. This update is for the USB interface chip. In theory, it allows for UNO to emulate USB HID, such as MIDI/Joystick/Keyboard.
