Arduino Duemilanove - ATMEGA 328



Were very happy to announce that the Arduino Duemilanove has been upgraded to a more powerful microcontroller: the ATmega328. Its fully compatible with the previous ATmega168, but with twice the memory. That includes flash memory for storing sketches (32 KB instead of 16 KB), RAM for holding variables (2KB instead of 1KB) and EEPROM for saving data when turning off the board (1 KB instead of 512 bytes). Weve also raised the speed (in the bootloader) for uploading new sketches from 19200 baud to 57600 baud. - (from Arduino blog)

The latest version of the USB boards. Allows for automatic reset of the board by the Arduino software when uploading. Contains a low dropout power supply (which accepts 6-12V), and has overcurrent protection for the USB connection.

Overview The Arduino Duemilanove ("2009") is a microcontroller board based on the ATmega168 (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. "Duemilanove" means 2009 in Italian and is named after the year of its release. The Duemilanove is the latest in a series of USB Arduino boards;
