ENC28J60 Breakout board.

Hi.

I have been studying / playing with Arduino (a Mega 2560 board) for 6 months now.

Now I am trying to connect it to a network using a breakout board like this one.

I've read at least the following sites/pages/docs:

http://arduino.cc/forum/index.php/topic,112323.0.html

The connections between Arduino <--> ENC28J60 is as follows:

ENC28J60 Arduino

CLKOUT NC
WOL NC
SO 50
SI 51
SCK 52
CS 53
RESET RESET
VCC 3v3
Gnd Gnd

For testing I downloaded this library and tried to run the Web Server sketch to no avail.

When powered there's a red led in the breakout board that lights up but the statuses leds on the RJ 45 connector does not lights up (no matter whether I connect it to my router or my computer directly).

Questions:

  • Simply connecting it to my router / computer should cause the statuses leds to blink / flash, no?
  • Does anyone knows if the cable used to connect it to the computer/router makes any difference? I mean, does it need to be a crossover cable?
  • Does anyone knows whether there's an easy way to test this breakout board without complicated/expensive hardware / software? (I'm starting to believe it is defective)

Any help will be appreciated.

my advice would be to give the board a good looking over. I had a similar problem and it did turn out to be bad soldering on the breakout board. And yes the link lights on the cable connector should come on when the board has power and Ethernet is connected to a lan.

Thanks for your answer, but I am afraid I still have some other issue with this breakout board (I've checked all the resistors but none looked suspicious. Just in case, I attached a picture)

I still don't know whether a crossover cable is required or not (I'll get one to test)

Thanks.
