EtherMega 100 Arduino Mega 2560 compatible with onboard Ethernet

The ultimate network connected Arduino compatible board: combining an ATmega2560 MCU, onboard Wiznet based Ethernet, an ATmega16u2 USB serial converter, a microSD card slot, a MAC address ROM, 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

We’ve even added a micro SD card slot so you can store web content on the card, or log data to it

It also includes a MAC address ROM containing a unique address, so that you don’t need to specify a bogus MAC address in your sketch and change it for every board Instead, your sketch can simply load the MAC address on startup using our example code

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 include:

• Gold plated PCB
• Top and bottom parts overlays
• Powerful and versatile 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 and we also have the 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
• Optional Power over Ethernet support, both cheapie DIY or full 802 3af standards compliant
• Ethernet activity indicators on both the PCB and the jack
• 10/100base T auto selection
• MAC address ROM
• Fully compatible with standard Ethernet library
• Reset management chip
• Fixed SPI behavior on Ethernet chipset
• Robust power filtering

Note that just like our , the EtherMega provides a number of options for different Power over Ethernet methods You can use the supplied jumpers and feed 7 28Vdc down the wire for cheap DIY version, or you can use our along with a proper commercial PoE injector or switch that supplies 48Vdc It’s up to you
