A000074, Arduino Ethernet Rev3 with PoE - Development Kit based on the ATmega328 8-bit ATmega AVR MCU

A000074, Arduino Ethernet Rev3 with PoE Development Kit can also be powered via an external power supply, an optional Power over Ethernet (PoE) module or by using a FTDI cable/USB Serial connector. External power can come either from an AC to DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The optional PoE module is designed to extract power from a conventional twisted pair Category 5 Ethernet cable
