M.2 USB 3.0 WWAN Adapter

This adapter converts a 30x42 mm NGFF B-key WWAN module to a USB 3.0 connection for desktop or laptop PCs. It accepts modules such as the DW5811e, DW5816E, EM7455 and L860-GL. The board includes a Nano-SIM slot and a module fixing screw hole. No external power is required.

Four external antennas included

The package supplies four antennas that attach to the installed WWAN module. They provide the RF paths needed for 2G, 3G and 4G LTE networks. Users must still install the correct driver software for their specific M.2 card before the connection will work.

Compact 87x32 mm PCB with USB 3.0 plug

The small board measures 87 by 32 mm and plugs directly into a standard USB 3.0 port. Its integrated screw hole secures the M.2 module firmly during transport or vibration. The design suits builders adding cellular connectivity to systems without an internal M.2 Key-B slot.

Questions about this item

Will the SIM-card slot or M.2 B-key connector on this adapter need replacement later?

The nano-SIM slot and B-key connector are passive mechanical parts rated for many insertion cycles; they do not wear out under normal use.

What limit appears first when the adapter runs continuously at USB 3.0 speeds?

Thermal throttling of the installed WWAN module is the first bottleneck; the adapter board itself adds no active circuitry that would saturate first.

How much heat or noise does the adapter produce during all-day operation?

The bare adapter is silent and generates negligible heat; all warmth and power draw come from the inserted WWAN card and its four antennas.
