GW16140 / GW16141 / GW16147 / GW16148 / GW16151 Mini-PCIe to M.2 Cellular Modem Adapters and WiFi radios

These adapters convert a Mini-PCIe slot on the Gateworks SBC to various M.2 sockets designed primarily for Cellular Modems and WiFi radios. No active circuitry exists so the signals must be provided on the baseboard MiniPCIe socket to be useful. The exception is that SIM sockets require no baseboard functionality as the signals pass directly from the SIM sockets to the M.2 socket pins.

This page is specifically about the M.2 adapter, but note Gateworks has a dedicated Cellular Modem Wiki Page

This wiki page describes the technical usage details of the adapter. For pictures, datasheets and ordering, please view the ​GW16140/GW16141 Product Page on the main Gateworks Website.

It is important to compare the M.2 Pinout of the modem to the M.2 pinout of the GW1614x to verify no pin conflicts.
