A500V2 Expansion Port & ENC28J60 Modules Blues :-)

Yesterday I received my ENC28J60 modules after 5 weeks of waiting.
  I ordered the 3.3V with a 10-pin headermodules as shown in the expansion port Wiki.
  The modules I got are  5V, have a 12-pin header and the SI & INT signal seems missing. See picture:
  EXTERNAL LINK   
  I've contacted the eBay seller yesterday. But even if he send them today, I have to wait another 5 weeks. :)
 
  Then I posted this in the Vampire Facebook group.
  One member Leigh 'Perc' Rus gave me some links to Arduino & RPI forums where they discussed this problem.
 
  I have read the info on that forums.
  It seems that:
  LNT = INT
  ST = SI
  Q3 = 3.3V
 
  The board also has a SCK and CLK pin
  As I remembered from the SDNET readme one should use the SCK pin!
 
  I've connected now my ENC module to these pins like the expansion port Wiki says.
  I triple checked every connection on the ENC28J60 module and on the A500 V2+ expansion header.
  Layout as from the Wiki:
  Expansion Connector.  ENCJ2860 Module
  8 (MISO)              So
  1 (MOSI).              Si
  3 (nCS1).              CS
  6 (CLK).              SCK
  5 (IRQ)                INT
  7 (GND).              GND
  2 (+3.3V).            VCC
 
  EXTERNAL LINK   
  EXTERNAL LINK   
 
And what happened?
 
  It worked without as it should :)
 
  I guess that the factory misspelled the characters. Just look good at ST & SI, Q3 & 3.3V and LNT & INT. For users not familiar with the Latin alphabet an error can easily be made. The mingled characters and numbers resemble one an other a bit :)
 
  The Apollo Team should add this variation of the ENC module info to their Wiki. :)

I bet there are a few people who got these and thought they wouldn't work.

Glad you got it working  in the end!

Thanks Again Leigh :)
I wanted to share the info here because as you said there are certainly more people who have this ENC28J60 variation!
And this info is also usable for an SDNET solution with the ENC module.
