RE: high power consumption in ethernet mode
I have the same problem.
I builded my own board (PIC18f66j60), after the example of PICDEM.net2 board, using for voltage stabilizer LM317T (3.17 VDC stabilized on the board )with an output current rating up to 1.5 A.
When the ethernet module is on, conected to the router or not, its current on the centertap of the RJ45 connector (TS8P8C-PCB-TRAF) is 90 mA.The ethernet module is configured for ping response, for now, and working. The entire board current consummtion is 150 mA. The LM317T gets hot and the pic also, but not as much.
If I programm the board to light an led from the RJ45 connector, LEDA for example, the board current consumtion is 6 mA.
If somebody has any ideas for debugging please share.
