NGFF M.2 Key B to USB 3.0 Riser Board, 3G/4G LTE WWAN Module USB3.0 Network Adapter with Universal 6Pin & 8Pin Dual SIM Card Slot

This NGFF M.2 Key B to USB 3.0 riser board is a dedicated converter for Socket 2 USB-based WWAN cellular modules, allowing you to turn spare M.2 3G/4G LTE modules into portable USB mobile network adapters for desktops, laptops, mini PCs and single-board computers.

Equipped with dual universal SIM card slots supporting both 6Pin standard SIM and 8Pin Nano SIM standards, it eliminates SIM size mismatch issues and supports dual-SIM standby for easy switching between different mobile data plans. The standard M.2 Key B slot accepts 3042 and 3052 dimension WWAN modules, covering mainstream industrial and consumer 4G LTE modules from Huawei, Sierra Wireless, Quectel, Fibocom and more.

Built with USB 3.0 high-speed circuitry, it delivers stable cellular broadband performance and supports auxiliary GPS signal output from compatible WWAN modules for positioning applications. The PCB adopts gold-plated contacts for anti-oxidation and long-term stable signal transmission, ideal for outdoor monitoring, industrial IoT, portable mobile office and test bench module debugging.

Powered entirely by the USB 3.0 interface, no external DC power adapter is needed for plug-and-play operation. The adapter itself requires no extra software; simply install the driver matching your M.2 cellular module to access mobile internet instantly. Compact PCB layout saves space for portable deployment, with mounting holes for fixed installation on equipment casings.

Perfect for DIY portable 4G hotspots, industrial IoT data transmission, notebook WWAN module testing, and adding cellular connectivity to desktop PCs without built-in M.2 slots.
