PCIe Mini Card / mSATA

The socket at location J8 accepts a full-height PCI Express Mini Card or an mSATA module.
The PCIe Mini Card 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, flash data
storage, and other cards for added flexibility. An Intel WiFi Link 5300 PCI Express Mini Card
(VL-WD10-CBN) is available from VersaLogic. 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 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 Card or mSATA module to the on-board standoffs, use two M2.5 x 6mm pan
head Philips nylon screws. These screws are available in quantities of 10 in the VL-HDW-108
hardware kit from VersaLogic.
