I want to replace a preinstalled Qualcomm Atheros WiFi/Bluetooth M.2 2230 card on my motherboard (ASUS Maximus VIII Impact) with another that has better driver support. This is what the card I want to replace looks like.
As you can see, its edge connector has all of its contacts (the copper/gold metal strips at the end). I want to swap this card with an Intel 8265 M.2 2230 card that looks like this.
But this card seems to be missing contacts. Why does this card have fewer contacts than the preinstalled card and will this cause problems when I swap out the old one for the new one?
