NGFF M.2 Key-B WWAN to USB adapter

This adapter converts a Key-B WWAN module to a USB 3.0 connection for laptop use. It includes an integrated SIM card slot so the modem and SIM work together. The device is designed for testing WWAN cards without opening the laptop chassis. No extra drivers are required beyond the WWAN module's own software.

Bundled SIM slot and WWAN socket

The built-in SIM slot lets you insert the carrier card alongside the WWAN module in one step. The Key-B socket accepts modules such as the MU736, ME936, ME906 series and Sierra Wireless EM7305, EM7345, EM7355 and EM7430. A SIM card alone will not activate the adapter; both cards must be present. The board does not support WLAN-only cards or SSD storage.

Compact riser card for bench testing

The black PCB measures 11.0 by 1.0 by 11.0 inches and weighs 0.01 kilograms. Its USB 3.0 interface plugs directly into a laptop port for quick module swaps. The layout exposes the M.2 Key-B edge connector and SIM tray for easy access during development. It is not suitable for users who need a WLAN adapter or an SSD enclosure.

Questions about this item

Does the SIM slot on the EP-026-HX need any periodic cleaning or replacement?

The SIM slot is a passive connector; it has no moving parts and requires no scheduled maintenance.

What speed limit appears first when the adapter runs continuously with a WWAN module?

The USB 3.0 interface and the module itself both cap sustained throughput at 3 megabits per second.

How much heat or noise does the EP-026-HX produce during all-day operation?

The adapter has no active cooling and draws minimal power, so it stays silent and barely warm.
