For the connection of external Mass Storage Devices, there is a standard male SATA connector, CN11.
This connector carries out directly SATA port#0 signals coming from Qseven

connector (pins 29, 31, 35, 37). In case the Qseven
connected, then this connector will not be usable.
Here following the signals related to SATA interface:
SATA0_TX+/SATA0_TX-: Serial ATA Channel #0 Transmit differential pair.
SATA0_RX+/SATA0_RX-: Serial ATA Channel #0 Receive differential pair.
The SATA channel #0 is switched with mSATA Slot (CN8). The switching is automatic, depending on the presence or not of
an mSATA device in the dedicated slot. This means that if a mSATA disk is plugged in the slot CN8, then the connector
CN11 will not work.
A dedicated power connector, CN 10, can be used to give supply to external Hard Disks (or Solid State
Disks) connected to the SATA male connector.
The dedicated power connector is a 4-pin male connector, type TKP p/n 4070I-04 or equivalent, with
pinout shown in the table on the left (it is the standard HDD Power connector).
Mating connector: TKP 8851-04 crimp housing with TKP 8851T crimp terminals.
An adapter cable for powering SATA disks from this connector is also contained inside the "Cross Platform
Development Kit 2.0". Please check par. 4.3 for further details.
