Take a look at the file Hardware/Enc28j60.h. You will find two #defines there (ENC28J60_LEDA, ENC28J60_LEDB) each one taking an initialization word for the LEDs. You can find the meaning of this word by reading the LED-section in the ENC28J60 datasheet. In case you just want to swap the LED-functions, just swap the two values and you will be fine.

Look at the mikrocontroller.net-Forum. Although it's a German forum, you can also post there on english since there are a few english speaking people (including me ;)). You can also send me an EMail or something like that (See Wiki:General disclaimer).

You can freely modify the existing application. But you can also add other applications to the stack. Unfortunately there isn't so much space left in the Program-space which will make it hard to add a useful second application.

The used LM1117 needs at least 4.4V to generate the necessary 3.3V used in the circuit. The maximum input voltage is about 7V, mainly dependent on how much current you will draw on the 3.3V line.

It needs about 150mA, where most of this current is drawn by the ENC28J60 and the transformers connected to it. Since the ENC28J60 does also send current through those transformers, the current is not dependent on any send/receive activity.

Durch den relativ hohen Strom, der durch den ENC28J60 in den Ethernet-Übertrager fließt ist eine Erwärmung des ENC28J60 völlig normal. Solange der Chip ohne Brandwunden berührt werden kann, ist alles im grünen Bereich.

No there is no specific reason, at least no financial one. Just that I don't have to care about people asking me about circuit-boards or parts, because IT-WNS is providing them.

The board was originally designed to use it with the Magjack SI-60024-F. But there is a layout-alternative for using the HALO HFJ11-2450E-L12 and ERNI Modular Jack M3D01-203199. Thanks go to Thomas Heldt for this layout.
