Mini PCIe to PCIe X1 4G LTE Adapter Card with SIM Card Slot & Dual Antennas, Supports 3G/4G/LTE Wireless Module for Desktop PC

This Mini PCIe to PCIe X1 conversion adapter is specially designed to install Mini PCIe 3G/4G/LTE cellular wireless modules into ordinary desktop computers that lack native Mini PCIe slots. It converts the compact Mini PCIe interface into a universal PCI Express X1 slot that fits all standard PC motherboards.

The adapter comes with an independent full-size SIM card slot on the external baffle, allowing users to insert mobile operator SIM cards directly to access cellular data networks without extra wiring. Two external antenna ports are matched with signal antennas, effectively enhancing signal receiving sensitivity to avoid network disconnection or high latency in weak signal environments.

It supports all mainstream Mini PCIe form factor 4G LTE, 3G cellular communication modules, covering common industrial and commercial wireless modules. The built-in stable signal conversion chip ensures smooth data transmission between the 4G module and the motherboard without bandwidth congestion or hardware recognition failures.

Equipped with a standard full-height metal shielding bracket, it can be firmly mounted inside ATX, MATX and ITX desktop chassis. The metal housing effectively suppresses electromagnetic interference from graphics cards and power supplies, guaranteeing long-time stable cellular network operation.

It offers complete driver compatibility with all Windows versions and mainstream Linux systems. Widely applied in industrial control desktops, remote monitoring NVR hosts, offline industrial equipment and DIY desktop machines that require independent mobile cellular network access.
