= GW1614x Mini-PCIe to M.2 Adapter
[[PageOutline]]
These adapters convert a Mini-PCIe slot on the Gateworks SBC to a M.2 B-Key slot for a M.2 Cellular Modem with Dual SIM slots. The adapter also provides SIM support for slots without a SIM. 

This wiki page describes the technical usage details of the adapter. For pictures, datasheets and ordering, please view the [https://www.gateworks.com/products/mini-pcie-expansion-cards/gw1614x-mini-pcie-to-m2-adapter-card/ GW16140/GW16141 Product Page] on the main Gateworks Website.
