Purpose and compatibility

This adapter lets a desktop or embedded system use a USB-bus Mini PCIe WWAN or LTE module through a standard USB port. It accepts 2G, 3G, HSPA, GPS, WiMAX and LTE Mini Cards but does not support PCIe-bus cards such as Wi-Fi modules. A SIM card slot and external antenna are included for carrier connectivity.

What the bundle adds

The board provides a 6-pin or 8-pin SIM connector and an antenna lead so the installed modem can reach the mobile network. No Mini PCIe module or SIM card is supplied, so the buyer must source those separately. The adapter draws power from the USB port and requires no extra power connection.

Interface limits

Only Mini Cards with a USB interface work; PCIe-interface cards will not function in this adapter. The host operating system must already have the correct drivers for the specific WWAN module, as the adapter itself needs no driver. The board measures 9.0 by 4.50 by 1.90 centimetres and weighs 100 grams.

Questions about this item

Will the external USB port need replacement after heavy use?

The single USB port is a standard connector rated for typical insertion cycles; no special maintenance is required beyond keeping it clean and free of debris.

What limits sustained throughput when a WWAN card runs continuously?

The adapter only passes USB-bus Mini-Card signals, so the card's own USB 2.0 interface and the host USB port set the practical ceiling.

Does the board generate noticeable heat or draw extra power during all-day operation?

No additional power is needed beyond the USB bus, and the small 100 g PCB stays at ambient temperature under normal load.
