The GSM/GPRS/GPS-Shield can now also be used with the Arduino Mega2560. In addition to the Arduino Duemilanove and the Arduino Uno (both with ATmega328) it is thus the third Arduino platform that can be extended to GSM (mobile phone) and GPS (navigation). The Arduino Mega2560 replaces the Arduino Mega, it is based on the Atmega2560 with 256K flash memory and uses a 8U2 as Atmega as USB ↔ seriell converter.
