Description
The Freetronics EtherMega - the ultimate network-connected Arduino-compatible board. The Ethermega houses a ATmega2560 MCU and a Wiznet-based Ethernet. What's more, it also houses a ATmega8u2 USB-serial converter, a microSD card slot and Power-over-Ethernet support. Further it even has an onboard switchmode voltage regulator so it can run on up to 28V without overheating!
The EtherMega is a 100% Arduino Mega 2560 compatible board that can talk to the world. Do Twitter updates automatically, connect to web services, display sensor data online, and control devices using a web browser. The Freetronics EtherMega uses the same ATmega2560 as the Arduino Mega 2560. This means you have access to masses of RAM, flash memory, and I/O pins. The onboard Wiznet W5100 chip used by the official Arduino Ethernet Shield, means it's compatible with the Ethernet library. Any project you would previously have built with an Arduino Mega 2560 and an Ethernet shield stacked together, you can now do all in a single, integrated board.
We've even added a micro SD card slot so you can store web content on the card, or log data to it.
But it gets even better: we found space to squeeze in a small prototyping area, so now it's possible for you to build a complete, Internet-enabled Arduino device including your own custom parts all on a single board! You don't even need to use a prototyping shield for many projects.
