Compatibility Notes  

This cable is designed for connecting M.2 Key A modules (e.g., Wi-Fi/Bluetooth cards like Intel AX200 or similar) to PCIe 3.0 x1 host interfaces. The M.2 Key A connector supports PCIe x1 and USB 2.0 signals (for Bluetooth), ensuring full functionality of wireless modules. Ensure the host system’s PCIe slot supports PCIe 3.0 or earlier versions (2.0/1.0) for backward compatibility. The cable provides integrated power delivery, eliminating the need for separate power connectors for the M.2 Key A device. Note that some M.2 Key A modules may require additional USB connections for Bluetooth functionality; verify module specifications for compatibility. This cable is not suitable for M.2 Key M or Key B+M devices (e.g., NVMe SSDs). The Key A connector is specifically designed for wireless applications and may not support other protocols like SATA.  

Note: All specifications adhere to PCI-SIG PCIe 3.0 standards and M.2 Key A specifications (as defined by organizations like PCI-SIG and applicable standards bodies), ensuring interoperability with M.2 Key A modules and PCIe-based systems. For optimal performance, use high-quality cables with proper shielding to minimize signal degradation.
