Expand Your M.2 B+M Key Slot with Storage or WWAN Support

The M.2 E Key to M.2 B+M Key Adapter allows devices with an M.2 B/M Key interface (commonly used for NVMe SSDs or WWAN modules with PCI signal) to be connected to a host with an M.2 E Key slot (typically used for Wi-Fi, Bluetooth, and other wireless modules). This adapter is ideal for systems that only provide an E Key slot but require support for storage or WWAN modules. The USB signal required by Bluetooth can come from the B/M slot or be introduced externally.

Cautions Power off the system before installation/removal. This adapter only provides physical pin mapping; protocol incompatibility will prevent operation. For further technical details, consult the official M.2 specification or contact your hardware provider.
