ATmega328 Arduino Uno SMD Rev3 Evaluation Board

A000073 Arduino Uno SMD Rev3 Evaluation Board for ATmega328, 8-Bit Microcontroller with 32 KBytes In-System Programmable Flash

Arduino

The A000073 Arduino Uno SMD Rev3 is an evaluation board for ATmega328.

Product Description

The Arduino Uno SMD R3 is a microcontroller board based on the ATmega328. 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.

Features
  • Microcontroller: ATmega328
  • Operating Voltage: 5V
  • Input Voltage (recommended): 7-12V
  • Maximum supply voltage (not recommended): 20V
  • Digital I/O Pins: 14 (of which 6 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 (ATmega328)
  • EEPROM: 1 KB (ATmega328)
  • Clock Speed: 16 MHz
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.
