M.2 PCIe SSD Socket (M-KEY) Connector: J9
The Elton baseboard is equipped with an M-keyed connector.
An M.2 SSD is "keyed" to prevent the insertion of a card connector to an incompatible socket on the host.
There are three keys that are commonly used: B, M, and B+M with the key type typically labeled on or near
the edge of the gold-plated fingers on the connector of the SSD.
One mounting standoff at the far end of the module installation site is not connected to Ground. The pinouts
for the connector are specified below.
