PCIe M.2 SSD Socket (M-KEY) Connector: J19
The Floyd carrier board is equipped with an M.2 PCIe SSD M-keyed connector for 2280 sized modules for
storage applications. An M.2 SSD is "keyed" to prevent the insertion of a card connector to an incompatible
socket on the board.
The PCIe link routing from the Jetson module to the M.2 socket varies according to the Floyd model.
FLD-BB01
:
The PCIe x4 link from the Jetson module is routed to a switch which provies 3 PCIe x1
links for the M.2 socket, PCIe minicard socket, and 2
nd
Ethernet port.
FLD-BB02
:
The x4 PCIe link is directly connected to the M.2 socket for maximum bandwidth. The
minicard and 2
nd
Ethernet port are not present. With the Jetson Xavier NX module installed,
an additional PCIe x1 lane interface can be mapped from the NX to the second Ethernet
(contact Diamond Systems Corp for custom build options).
