GW16140 / GW16141 / GW16147 / GW16148 Mini-PCIe to M.2 Cellular Modem Adapters

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 page is specifically about the M.2 adapter, but note Gateworks has a dedicated Cellular Modem Wiki Page f This adapter passes through USB signalling designed primarily for Cellular / LTE Modems. The adapter does not pass through any PCIe signalling. This adapter will not work for any 4xPCIe NVME M.2 cards. Each Mini-PCIe slot only has 1xPCIe and PCIe signalling is not passed through.

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.

There are 2 derivations of the GW1614x shown below.

GW16141 - USB 3.0

This is a USB 3.0 B-Key version. USB 3.0 is only supported by certain slots on Newport SBCs, USB 3.0 is not supported on Ventana. For Ventana boards always use GW16140.

• M.2 B-Key
• Do not use on Ventana family
• USB 3.0 slots on Newport SBCs - Note the USB 3.0 signals overlap with the PCIe signals so some boards have a mux to allow the slot to be configured for either PCIe signaling or USB 3.0 signaling. See link here for controlling the mux using HWCONFIG.
  • GW6100 - J6 (PCIe/USB 3.0 mux)
  • GW6200 - J6 (PCIe/USB 3.0 mux)
  • GW6300 - J11 (PCIe/USB 3.0 mux)
  • GW6400 - J12 (no mux - only supports USB 3.0)
• USB 3.0
  • Pin 29 USB3 RX-
  • Pin 31 USB3 RX+
  • Pin 35 USB3 TX-
  • Pin 37 USB3 TX+
• Power and Ground - Various M.2 Pins per M.2 B-Key Spec
• W_Disable Pin 8
• SIM 1 - Pin 30,32,34,36
• SIM 2 - Pin 42,44,46,48

GW16147 - USB 2.0 & PCIe

This was primarily designed for 5G cellular modems, where the USB 2.0 is used for control and the PCIe for data.

This is almost the same as the GW16140, but has the following M.2 pins also connected for PCIe:

• Pin 41 - PERN0
• Pin 43 - PERP0
• Pin 53 - REFCLKN
• Pin 55 - REFCLKP
• Pin 47 - PETN0
• Pin 49 - PETP0
• Pin 50 - PERST

GW16148 - 1x PCIe for NVME SSDs

This was primarily designed for NVME Storage drives. This card uses 1x PCIe lane.
