[MinnowBoard] Wifi/Bluetooth questions

[ericolv at cox.net]

I have a MBM and a Silverjaw Lure, populated with a 120gb ssd. I installed the 0.80 64-bit version of the firmware and  I'm running Windows 8.1 embedded.  So far, all is working well. I have an open mPCI-E slot on the silverjaw and was looking at a Wifi/Bluetooth card, such as the Intel Dual Band Wireless-AC 7260 WiFi Bluetooth card.   

Anyone else have experience with this card or perhaps a different one I should consider?  

Any problems or pitfalls to be aware of?

Also, what is the max input voltage the MBM can safely handle?  I know the board takes a 5V input but can it handle a 7.5V input?

Thanks
