question about a resistor on ethernet shield

by tge1986 on Thu Sep 24, 2009 12:35 pm

I have a question about the pull-up resistor fro the wiznet module on the ethernet shield that is connected to the /scs pin. I have created my own ethernet arduino clone board and on that resistor i measure 5v not the 3.3, however on the ethernet shield it is only 3.3v. Any ideas what could be causing this? my schematic pretty much matches the ethernet shield.

Which version do you have? As far as I can tell you may have the wrong regulator or maybe wrong wiring. Can you post large clear pictures of your shield?
