SATA Interface
The Hawk provides one serial ATA (SATA) port that communicates at a rate of up to 3.0 Gbits/s
(SATA II). The SATA connector at baseboard location J2 is a SATA II-compatible right-angle
connector with latching capability. Power to SATA drive is supplied by the ATX power supply.
Note that the standard SATA drive power connector is different from the common 4-pin Molex
connector used on IDE drives. Most current ATX power supplies provide SATA connectors, and
many SATA drives provide both types of power connectors. If the power supply you are using
does not provide SATA connectors, adapters are available.
Mini PCIe / mSATA Socket
The socket at location J7 accepts a full- or half-height Mini PCI Express (PCIe) card or an
mSATA module.
The Mini PCIe interface includes one PCIe x1 lane, one USB 2.0 channel, and the SMBus
interface. The socket is compatible with plug-in Wi-Fi modems, GPS receivers, MIL-STD-1553,
flash data storage, and other cards for added flexibility. An Intel Wi-Fi Link 5300 Mini PCIe
card (VL-WD10-CBN) is available from VersaLogic. A Wi-Fi antenna (VL-CBR-ANT01) and a
12" Wi-Fi card to bulkhead RP-SMA transition cable (VL-CBR-0201) are also available. For
more information, contact Sales@VersaLogic.com.
The VL-MPEs-F1E series of mSATA modules provide flash storage of 4 GB, 16 GB, or 32 GB.
To secure a Mini PCIe card or mSATA module to the on-board standoffs, use two M2.5 x 6 mm
pan head Philips nylon screws. These screws are available in quantities of 10 in the VL-HDW-
108 hardware kit from VersaLogic.
