Original new version of UNOs R3 development board official version ATmega16U2
UNOs R3 is the latest easy-to-use open source controller launched in 2012. Compared with UNOs, there is no major change in hardware. The biggest difference lies in the USB-to-serial circuit part, which uses an ATMega16U2 single-chip microcomputer. Improve, the software part is the same as before, no major changes.
Function:
1. Pin changes: Two I2C pins (SDA and SCL, just a copy of Analog 4 and 5, not an additional I2C interface) are added beside the AREF pin, and two pins are also added beside RESET, one is IOREF , which can make the expansion board adapt to the on-board voltage. This pin just tells the expansion board what the current on-board voltage is (for example, UNO is 5V, which can be regarded as a copy of the power pin, and does not provide level pull-up), and the other is the future Standby pins to be used.
2. More stable RESET circuit. The position of the RESET button has also changed, and it has been 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 can make your code run faster, this update is for USB interface chip, theoretically it allows UNOs to simulate USB HID, such as MIDI/ Joystick/Keyboard.
