Hi Hoppy,
You may remember that the M2 card is offered in a few different flavours for different PC slots.

M.2, also known as NGFF (Next Generation Form Factor) is the successor of the mSATA standard for expansion cards. M.2 is very flexible and is widely used as an option for additional storage on the today laptop’s motherboards. It can vary in its size – at this point, commercially available are 30mm, 42mm, 60mm, 80mm, and 110mm lengths, which are commonly expressed like ‘2230’ (22mm wide, 30mm long), ‘2242’ (22mm wide, 42mm long), etc.
There are also three different types of “keys”, which purpose is to prevent the use of inappropriate M.2s – B, M and B&M

You need to choose your M2 PCB to match the installed slot. That means the internal wiring of the M2 contacts varies depending on which slot the PC has.
Most cards (e.g. SSD, etc) come B+M keyed so they fit into either slot on the mobo.
