Does "Mega Sensor Shield V2.4" pass icsp through?

I wonder if "Mega Sensor Shield V2.4" [url=http://www.dfrobot.com/index.php?route=product/product&product_id=560]http://www.dfrobot.com/index.php?route=product/product&product_id=560[/url]
pass ICSP through
This shield is best i see so far, very clever design with possibility to put another shield on top
I want to put Arduino Wifi Shield in top of "Mega Sensor Shield V2.4" so my question is will it properly connect to ICSP bus?
I understand that it is probably the case. It is hard to see from pictures
But i can not see ICSP on back side of the board which suppose to connect to arduino ICSP header
So will my Wifi shield will work on top of "Mega Sensor Shield V2.4"

2014-08-21 03:46:14 So close but probably will not work for me :(
I done some investigation
I have Arduino Due which very close to Mega and have same layout
but SPI pins are different on Due
"Mega Sensor Shield V2.4" probably use Mega 50-53 pins for SPI
And on Due it is only ICSP and i do not see way to remap it
i wish "Mega Sensor Shield V2.4" take its SPI from ICSP header
I will think if i can rewire this on board otherwise this shield not going to work
which is very sad because this board is best for me and i do not see good analogs :(
So close essenti

You can check the schematics here:

SPI is connected, so should be ICSP. ICSP is just SPI. SPI pins can be connected on the side pins directly as well . The connector is just a very good standard to offer compatibility with several devices. But it does not need to be connected on the bottom as well
cheers Jose
