PCI Express Mini Card Socket
The PCI Express Mini Card connector at J2 accepts a full-height PCI Express Mini Card. The
interface includes one PCIe x1 lane, one USB 2.0 channel, and the SMBus interface. The socket
is compatible with 802.11a/b/g Wi-Fi network adapters that operate in both the 2.4 and 5.0 GHz
spectra, GPS radio cards that enable time/date stamps and global location applications, 3G
modems, solid-state drives (SSDs), and USB (2.0) cards.
An optional PCI Express WiFi Mini Card is available for the VL-EPHs-P1 as VersaLogic part
number VL-WD10-CBN. A WiFi antenna (VL-CBR-ANT01) and a 12" WiFi card to bulkhead
RP-SMA transition cable (VL-CBR-0201) are also available. For more information, contact
.
To secure a Mini Card to the VL-EPHs-P1 use two screws (M2 x 5mm, Philips, pan head, 4mm,
stainless) and two washers (M2, split lock, OD 4.4mm, stainless). Screw and washer sets are
available in 10-count packages as part number VL-HDW-107.
