Arduino Ethernet Rev3 with PoE
Arduino seems to rely extensively on ATmega328 by accompanying the microcontroller, this time, with Arduino Ethernet Rev3 with PoE. Featuring 14 Digital I/O pins including 6 analog inputs, Ethernet promises a lot. The board facilitates a power jack, reset-button, RJ45 connectivity, 16MHz crystal oscillator, and ICSP header. The auto-reset feature helps continuous proceedings without requiring to stop the system before uploading the sketches.

Arduino Ethernet Rev3 with PoE
The board facilities the additional power for Ethernet module (optional). The Ethernet is not like you mostly see with various other boards. Ethernet Rec3 lacks the driver chip for USB-Serial, instead, there is a Wiznet Ethernet interface. The board comes with a MicroSD reader. It allows you to store files and retrieve them back from SD library.
The board facilitates the automatic upload of the sketches as it doesn’t require pressing the physical power button. The auto-reset features quicken things and eliminate any chances of stoppages in the proceedings.
