M.2 NGFF Key B to Mini PCI-E WWAN Adapter, M2 to Mini PCIe Converter Riser for 3G/4G/5G LTE WiMAX CDMA GSM WWLAN Cellular Modem Module

This NGFF M.2 Key B to Mini PCI-E converter riser solves the hardware compatibility problem of installing modern M.2 cellular modules into legacy Mini PCIe slot notebooks and industrial mini hosts. It converts M.2 Socket 2 Key-B WWAN interface to standard Mini PCI-E slot, perfectly matching mainstream 3G, 4G LTE, 5G, WiMAX, CDMA and GSM wireless modem modules.

Adopting straight-through USB 2.0 signal wiring, it completely retains cellular data transmission, voice call and GPS positioning functions without signal attenuation. The PCB board supports three common M.2 module lengths: 3030, 3042 and 3052, covering most commercial and industrial WWAN modems from Quectel, Fibocom, Simcom and Sierra Wireless.

Gold-plated contact pins reduce contact resistance and anti-oxidation for long-term stable cellular connection. No extra external power supply required, powered directly via Mini PCIe slot bus voltage. It runs smoothly under Windows XP/7/10/11 and Linux embedded systems; only the driver for your cellular module needs to be installed, no extra adapter drivers needed.

Compact low-profile PCB design fits narrow notebook and embedded device internal space, ideal for industrial monitoring gateways, remote data acquisition terminals, old notebook cellular network upgrades and outdoor IoT wireless transmission equipment. Package includes mounting screws and screwdriver for one-step DIY installation.
