Enlarge your circuit board!
The fine people at Arduino have released the new, enhanced, extra jumbo Arduino Mega. Nicey!
It is a larger, more powerful Arduino board. It’s based on the on the ATmega1280 (datasheet), which has 128 KB of Flash (program) memory, 8 KB of RAM, and 4 KB of EEPROM. The board has 54 digital pins (of which 14 provide PWM output), 16 analog inputs, 4 hardware serial ports, I2C, and all other goodness you expect from an Arduino board. The Mega is compatible with most shields designed for the Duemilanove, and includes the same automatic power selection, auto-reset on upload, and pre-burned bootloader. The Mega will be appearing soon at distributors throughout the world. Check the buy page for the one closest to you.
