NGFF M.2 Key B to USB 3.0 Adapter Card with Dual Nano SIM Slots & Type-C Auxiliary Power, External Converter for 4G LTE 5G WWAN Cellular Module, Fits 3042/3052 M.2 Modems

This NGFF M.2 Key B to USB 3.0 adapter board is a professional conversion solution designed for M.2 4G LTE and 5G WWAN cellular modules, converting M.2 B-key interface to standard USB 3.0 output for desktops, mini PCs, industrial gateways and embedded IoT devices.

It adopts dual Nano SIM card push-pull slots, allowing users to install two operator SIM cards simultaneously. You can switch between two mobile networks via AT commands to realize network redundancy, avoiding offline risks caused by single carrier signal failure, perfect for remote monitoring, outdoor data transmission and unmanned equipment.

Equipped with exclusive Type-C auxiliary power input interface, this adapter effectively addresses the insufficient power supply issue of high-power 5G modules under heavy load. It provides stable sustained current to prevent disconnection, signal drop or module shutdown during high-speed data upload and download, greatly improving long-running reliability.

Compliant with USB 3.0 transmission standard up to 5Gbps bandwidth, the board delivers smooth cellular network performance with low latency, suitable for high-definition remote video, mass sensor data uploading and cloud real-time communication. It supports mainstream 3042 and 3052 size M.2 Key B modems from Quectel, Fibocom, Simcom and other brands.

Built-in multi-layer EMI shielding circuit reduces electromagnetic interference from PC hardware, ensuring steady cellular signal reception. Reserved dual SMA antenna ports allow external high-gain antennas to boost signal strength in weak coverage areas. Plug-and-play design supports Windows, Linux and macOS systems; only the corresponding driver for your cellular module needs to be installed.

Compact PCB layout saves installation space, widely applied to industrial control equipment, intelligent monitoring gateways, vehicle-mounted hosts, mini PC expansion and outdoor portable data transmission terminals. It is an essential accessory for IoT developers
