This circuit allows Arduino compatible boards to connect to Ethernet networks witch will allow it to be connected to the Internet , it's based on the ENC28J60 chip and with the available libraries it's very easy to build a small web server to control and monitor your application over the Internet .
- standard RJ-45 connector, with an integrated line transformer.
- Three LED indicators for power , link status and data packets transmission.
- Reset switch for both the ENC82J60 chip and the Arduino board.
- Power selection jumper for internal 5V power or external power (from the Arduino main board) .
4-Data Rx/Tx LED.
5-Link status LED.
7-Power selection jumper.
Note : this circuit doesn't support power over Ethernet standard PoE .
