aimeilai M.2 B-Key 5G WWAN Adapter Dual Bus USB3.0 PCIe

SKU CH-A7M2-TY5A4

Passive adapter lets desktop PCs use 30x42 or 30x52 M.2 B-key 5G modules via USB 3.0 and PCIe 1x with dual Nano-SIM slots and included antennas

  • TypeAdapter
  • Converts M.2 B-Key 5G modules to USB 3.0 and PCIe x1 for desktop PCs
  • Dual bus interface uses PCI Express and USB 3.0 simultaneously
  • Fits 30x42 mm and 30x52 mm M.2 B-Key 3G, 4G and 5G modules
  • Two Nano SIM slots allow dual carrier operation
  • Includes U.FL to SMA pigtail cables plus four 2.4/5 GHz antennas

M.2 B-Key 5G WWAN Adapter with Dual Bus

The aimeilai adapter converts an M.2 B-key 3G, 4G or 5G module to both a USB 3.0 port and a standard PCI Express 1x slot. It accepts 30x42 mm and 30x52 mm modules and includes dual nano-SIM slots plus U.FL to SMA pigtail cables for external antennas. The package supplies the PCB adapter, four 2.4/5G antennas, a metal bracket, a USB 3.0 cable and mounting screws.

Desktop builders adding cellular connectivity

This adapter suits builders who want to install a 5G or 4G WWAN card in a desktop PC using either the PCIe lane or the USB 3.0 connection. It is not for users who need to connect M.2 Key M, Key E or Key A/E modules, nor for laptops or embedded systems that lack a full-size PCIe slot and a free USB 3.0 header.

Dual PCIe and USB 3.0 bus interface

The single specification that decides compatibility is the dual-bus design: the adapter simultaneously presents the M.2 module to the system through both a PCI Express 1x lane and a USB 3.0 link. Your motherboard must provide both a free PCIe x1 slot and an internal USB 3.0 header for the adapter to function as intended.

Questions about this item

Will the U.FL/IPX4 pigtail cables need replacing after repeated antenna swaps?

The U.FL/IPX4 to SMA male pigtail cables are rated for limited mating cycles; plan to replace them if you frequently change the 2.4G/5G antennas.

Which bus saturates first when a 5G module runs at full throughput on the PCIe x1 lane?

The single PCIe 1x lane typically reaches its bandwidth ceiling before the USB 3.0 path, so sustained 5G speeds will be limited by the PCIe interface.

How warm does the metal bracket get when the adapter powers a 5G module continuously all day?

The passive PCBA and metal bracket dissipate heat from the module; expect noticeable warmth but no active cooling is included.
