Specifications
Uses an ATmega328P
Rev 3 boards now have an added SDA and SCL pin near AREF pin and two other new pins placed near the RESET pin.
The IOREF pin enables shields to adapt to the voltage provided from the board
Has a stronger RESET circuit
ATMEGA 16U2 replaces the 8U2 found on the Rev 2 model
Operating Voltage: 5V
Input Voltage (recommended): 7~12V
Input Voltage (limits): 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 for 3.3V Pin: 50 mA
Flash Memory 32KB (ATmega328) of which 0.5KB is used by the bootloader
SRAM: 2KB (ATmega328)
EEPROM: 1KB (ATmega328)
Clock Speed: 16MHz
