a Pic to show how small these mini-pci modules really are - here is my Commell WiFi card next to a USB stick.
The Commell LV-677 has 2 onboard mini-pci slots, similar to what a Laptop has to accept, for example, a WiFi card.
With that in mind, I ordered a MP-954 GPS module, and a MP-2501 WiFi from Commell, for this application. Here's a few pics to show how these fit, and the compact size of this setup.
and it this one, you can see the WiFi antenna fitted to the Morid Cubid case, just enough space for it, and still allowing the lid to close proper.
I still need to fit the socket for the GPS antenna to the case, similar to the one for the WiFi, just on the opposite side.
A Few pics from the rear, without the WiFi antenna fitted, and with it fitted - looks rather nice, and ....well....small.
