To increase mass storage possibilities, it is possible to use
mSATA Solid State Disks, using the dedicate connector, CN8,
which is a standard 52pin miniPCI Express connector, type TE
1775861-4 or equivalent, H=4.0mm, with the pinout shown in
the table on the left.
Signals carried to mSATA slot are the following:
SATA0_TX+/SATA0_TX-: Serial ATA Channel #0 Transmit
differential pair.
SATA_RX+/SATA0_RX-: Serial ATA Channel # Receive differential pair.
mSATA_DET#: mSATA Presence Detection pin. This signal is driven low by mSATA disks
plugged in the CN8 slot. It is used to switch the SATA Channel #0 between the mSATA slot
and the SATA Connector CN11 (when an mSATA disk is plugged into CN8, then CN11 will
be disabled).
When a mSATA disk is plugged into the slot, a red LED (D2) will light.
Please be aware that mSATA slot will work only in case the Qseven
®
Channel #0 on Qseven connector (pins 29, 31, 35, 37). In case the Qseven
doesn't have these signals connected, then this slot will not be usable.
A red LED, D25, is located on the PCB near the mSATA slot, between the SD Card and the SIM Card
slots; it will blink to signal activity (i.e. data transfers) on one or both the SATA Channels (SATA
connectors and/or mSATA Slot).
