EtherMega Ethernet Arduino Compatible Microcontroller
The ultimate network-connected Arduino-compatible board: combining an ATmega2560 MCU,
onboard Wiznet-based Ethernet, an ATmega16u2 USB-serial converter, a microSD card slot, and
Power-over-Ethernet support, and even 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, serve web pages, 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 so it has masses of RAM, flash memory, and I/O pins, and also includes the same
Wiznet W5100 chip used by the official Arduino Ethernet Shield, so it's 100% compatible with the
Ethernet library and sketches. 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.
A micro SD card slot has been added so you can store web content on the card, or log data to it. But it
gets even better with space to squeeze in a small prototyping area, so now it's possible 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.
Features
• Gold-plated PCB
• Top and bottom parts overlays
• Top-spec ATmega2560 MCU
• Micro-USB connector: no more shorts against shields from the USB jack! (Please note that the
Ethernet Jack can touch some wide shields, they can be raised up with Stackable Header Sets
and also have the ProtoShield Short which can sit beside it.)
• Switchmode voltage regulator for wide input voltage range
• D13 pin isolated with a MOSFET so you can use it as an input
