M.2 B Key NGFF to USB3.0 Adapter Riser for 3G/4G/5G Cellular Module, Dual Nano SIM Card Slot, LED Power Indicator, Support 3042 & 3052 Size M.2 Modem Card, Portable Cellular Network Expansion Card for

This M.2 NGFF to USB3.0 adapter riser is designed exclusively for B Key formatted 3042 and 3052 size 3G, 4G and 5G cellular modem modules. It converts the dedicated M.2 cellular interface into a standard USB 3.0 port, allowing users to use industrial-grade M.2 5G/4G modules on desktops, mini hosts and embedded devices without native M.2 slots.

The board carries dual independent Nano SIM card slots, enabling users to insert two different operator SIM cards simultaneously. You can easily switch network access by software configuration, ideal for scenarios requiring backup network or cross-operator signal testing. A visible LED power light is reserved on the PCB; it lights up after power-on to confirm normal power supply and module recognition, helping users quickly judge connection faults.

Adopting USB 3.0 high-speed transmission channel, the adapter fully releases the high throughput performance of 5G modules, supporting smooth high-speed downloading, remote monitoring and industrial data transmission. The circuit integrates multi-layer protection including overcurrent, short circuit and electrostatic prevention, effectively shielding signal interference in complex industrial environments.

Only compatible with M.2 B Key cellular modules (3042/3052 dimension), not fit for NVMe or SATA SSD M.2 drives. No complicated BIOS setup required; mainstream Windows and Linux systems automatically identify the adapter after plugging into USB ports.

Perfect for industrial routers, video surveillance hosts, mobile test equipment and DIY portable 5G broadband workstations. It is an essential accessory for communication engineers and embedded developers to deploy and test M.2 cellular modules.
