The M.2 SATA interface is provided for SATA SSD access using the PS-side bank 505 GTR transceiver.
This Figure
shows M.2 connector U40.
The socket 2 SATA adapter pinout with key M is shown in
Table: M.2 Connector U40 Pinout
. SATA-A data connection is used for TX and SATA-B for RX. The M.2 connector U40 is a type 2242 (active component section 22 mm wide with overall length 42 mm form factor) used on socket 2.
