SATA 2.0 connectors
The V2M-Juno r2 motherboard provides two SATA 2.0 connectors that connect to an on-board SATA 2.0
controller with a one-lane connection to the PCIe switch.
Note
The SATA 2.0 I/O voltage at the connectors is 1.8V.
The V2M-Juno r2 motherboard labels the SATA 2.0 connectors as
SATA0
and
SATA1
. The following
