= M.2 Form Factor = The M.2 Form Factor, previously known as NGFF or Next Generation Form Factor is another form factor other than Mini-PCIe. Gateworks uses Mini-PCIe connectors on most of their single board computers. There are many keying interfaces, with the most popular being B & M. Read more here: [https://en.wikipedia.org/wiki/M.2] Typically for a modem needing USB, this would utilize the B-Key which has PCIe ×2, SATA, USB 2.0 and 3.0, audio, UIM, HSIC, SSIC, I2C and SMBus. Even though these other signals are available, typically the modem will only require the USB signals. The M key has PCIe ×4, SATA and SMBUS. Gateworks does not have any Mini-PCIe slots with 4x PCIe lanes, thus utilizing an adapter will not necessarily provide the full set of signals. If it is required to use a M.2 on a Gateworks SBC, Gateworks sells the [https://www.gateworks.com/products/mini-pcie-expansion-cards/gw1614x-mini-pcie-to-m2-adapter-card/ GW16140 Mini-PCIe to M.2 Adapter]. == GW16140 Mini-PCIe to M.2 Adapter * https://www.gateworks.com/products/mini-pcie-expansion-cards/gw1614x-mini-pcie-to-m2-adapter-card/ [[Image(gw16140top.png,400px)]]
