Arduino Upgrade

[Ken]

For those of you who are working with the Arduino Duemilanove, you
might be interested in this announcement from Arduino about a
processor upgrade.

“We’re very happy to announce that the Arduino Duemilanove has been
upgraded to a more powerful microcontroller: the ATmega328. It’s 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).
We’ve also raised the speed (in the bootloader) for uploading new
sketches from 19200 baud to 57600 baud.

“Thanks to some tough negotiating by Gianluca Martino of Arduino and
Smart Projects, this won’t raise the price of the board. Look for
distributors to roll out the upgraded boards soon. Current Duemilanove
or other Arduino boards can be upgraded by replacing the ATmega168
with a bootloaded ATmega328 (you’ll need to buy a pre-bootloaded one
or use a hardware programmer). Be sure to select “Arduino w/
ATmega328″ from the Tools > Boards menu.”

Very cool. Just need to build a rom burner so you can install the
bootloader on the '328.
