What is the TransmogriShield described in https://allseenalliance.org/developers/develop/tutorial/arduino-and-gt202

Is the shield the product in http://store.arduino.cc/product/A000058?

I couldn't understand what role the shield is because the WiFi function is provided by GT202.

If I have already had GT202 kit and Arduino Due, I can connect Arduino Due to GT202 with SPI directy.

Why should the Arduino Due need to connect to the shield first and then make the shield connect to GT202?

The Transmogri Shield is needed for older revisions of the Arduino pin model where the SPI header is located near the center of the board and not on the outer pins. The GT-202 has all SPI pins on the outside with no SPI header in the middle. The "sandwiched" shield in the middle is needed to reroute the SPI pins to the outside. I would need to double check but I believe that all Arduino DUE models have the SPI header in the center, hence needing the Transmogri shield. The shield you provided a link to is NOT the transmogri shield.

You can find the one you need here: https://www.sparkfun.com/products/11469

If you do have an Arduino DUE model that DOES have the SPI pins on the outside then you wont need the additional shield. If Arduino does make such a model please inform us and we will update the documentation with that additional information.
