DFRduino Ethernet Shield V2.1 (Support Mega and

Micro SD)

SKU:DFR0125

INTRODUCTION

The DFRduino Ethernet Shield V2.1 is now released. This version of Ethernet Shield is

not only compatible with Mega 1280 and 2560, but also provides a Micro SD card slot

for reading/writing.

DFRduino Ethernet Shield V2.1 is fully compatible with Ardunio Ethernet Shield. With

the offical ethernet library, you can do exactly the same thing as the original one, but at

a more affordable price.

This Ethernet Shield provides an Arduino controller board with internet access. It is

based on the Wiznet W5100 ethernet chip. The Wiznet W5100 provides a network (IP)

stack capable of both TCP and UDP. It supports up to four simultaneous socket

connections. You can use the Ethernet library to write sketches which connect to the

internet using the shield.

You can connect the Ethernet Shield to an Arduino board using long wire-wrap headers

which extend through the shield. This keeps the pin layout intact and allows another

shield to be stacked on top.
