  • Microcontroller: ATmega328P
  • Operating voltage: DC 5V
  • Input voltage (recommended): DC 7~12V
  • Digital I/O pins: 14 (of which 14 provide PWM output)
  • Analog input pins: 6
  • DC current per I/O pin: 40 mA
  • DC current for 3.3V pin: 50 mA
  • Flash memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader
  • SRAM: 2 KB
  • EEPROM: 1 KB
  • Clock speed: 16 MHz


  • 1. Add two I2C pins(SDA and SCL) next to the AREF pin; and next to the RESET, add two pins: one is IOREF which allows the board to adapt to onboard voltage
  • (the IOREF pin is to tell how many the onboard voltage at present; e.g UNO is 5V that can be seen as copy of power supply pin and don't pull power level)
  • and the another is for future placeholder pin
  • 2. More stable RESET circuit; the RESET is moved to place closer to USB interface, thus more convenient to push
  • 3. ATmega328P replaces 8U2 so that UNO can simulate USB HID, e.g MIDI/Joystick/Keyboard

Package Includes:

  • 1 x UNO R3 Development Board
  • 1 x USB Cable
