The Arduino Uno SMD R3 is a microcontroller board based on the ATmega328 (datasheet).
It has 14 digital input/output pins (of which 6 can be used as PWM
outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB
connection, a power jack, an ICSP header, and a reset button. It
contains everything needed to support the microcontroller; simply
connect it to a computer with a USB cable or power it with a AC-to-DC
adapter or battery to get started.
The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.
Additional features coming with the R3 version are:
- ATmega16U2 instead 8U2 as USB-to-Serial converter.
- 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes.
- stronger RESET circuit.
Current per I/O Pin: 40 mA
Analog Input Pins: 6
Digital I/O Pins: 14 (of which 6 provide PWM output)
Maximum supply voltage (not recommended): 20V
Supply Voltage (recommended): 7-12V
