6.1.17 M.2 SATA Socket (J19)
The board provides mass storage support via an M.2 socket that supports SATA modules of size 2242. For the
pinouts shown, all TX/RX signals are with respect to the host. TX on the socket drives RX on the installed module,
and RX on the socket is driven by TX on the installed module. The mounting standoff at the far end of the module
installation site is not connected to ground.
The pinout of the connector is shown below:
