PCIe Mini Card / mSATA
The socket at location J14 accepts a full-height PCI Express Mini Card or an mSATA module.
The PCIe Mini Card interface includes one PCIe x1 lane, one hubbed 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. The VL-MPEs-F1E series of mSATA modules
provide flash storage of 4 GB, 16 GB, or 32 GB.
For more information on PCIe Mini Cards offered by VersaLogic, contact
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.
