ATmega328 network Shield problem

Hi, I wonder if anyone can help ? I have an ATMega328 with a Sensor Shield V5 attached if I attach my network shield - ENC28J60 to 10,11,12,13 , 3.3G and Grd on the shield I get power but no activity of the network shield , if I remove the sensor shield and connect up the same way directly to the atmega328 it works , could someone help me out and tell me where I'm going wrong ?

Network shield is this one

Sensor shield


It would appear that the sensor shield uses some of the same pins that the ethernet device uses. But, it’s impossible to say, as there is no technical documentation on that ebay ad.

Hi PaulS,
