Description

The ultimate network-connected Arduino-compatible board: combining an ATmega2560 MCU, onboard Wiznet-based Ethernet, an ATmega8u2 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!
Amazing.

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.

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 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

  • D13 Pin isolated with a mosfet so you can use it as an input
  • Reset management chip
  • Fixed SPI behaviour on Ethernet chipset
  • Robust power filtering
  • Gold Plated PCB.
  • Top and bottom parts overlays.
  • Top-Spec AT mega2560 MCU
  • Mini-USB connector: no more shorts against shields from the USB jack!
  • Switchmode voltage regulator for a wide input voltage range
  • Ethernet activity indicators on both the PCB and the jack.
  • 10/100base-T auto-selection.
  • Fully compatible with standard Ethernet library
