## Key Features Operating Voltage: 5v Input Voltage(Recommended):7~12v Input Voltage(Limited):6~20v Digital I/O Pins:14(of which 6 provide PWM output) Analog input pins:6 DC Current per I/O pin: 40Ma DC Current per 3.3V pin: 150Ma Flash memory:32KB(ATmega328) of which 0.5KB used by bootloader SRAM:2KB(ATmega328) EEPROM:1KB(ATmega328) Clock speed:16 MHz (For Arduino) UNO R3 is a easy-to-use type open source controller which was newly introduced in 2012. On the hardware, there is no big change compared with (For Arduino) UNO. The biggest difference lies in the part of USB converting to serial port circuit. The replacement is ATMega16U2 chip, so the cost may increase a little. The software is the same as before, no big change. Function: 1. pin change: Two I2C pins are added on the side of pin AREF (SDA and SCL, just the copy of Analog 4and 5, not an additional I2C interface). In addition, add 2 pins alongside the RESET, one is IOREF, which can make the expansion board adapt to board voltage. This pin is to tell expansion board the present onboard voltage (for example, when UNO is 5V, which can be seen as a copy of the power supply pin, does not provide a level pull-up) ;the other is an occupy pin to be used later. 2.More stable RESET circuit. The position of RESET key was also changed, moved to board corner near the USB interface, which is more convenient to press. 3.8U2 was replaced by ATmega16U2. This does not mean that there is R3 with 16K flash let your code run fast, this update is for USB interface chip. In theory, it let UNO can simulate USB HID such as MIDI/Joystick/Keyboard.
