### 4. Functionality

The EMXX-0102-W1-A71 functions as a signal and form factor conversion module, bridging the gap between legacy or existing mini PCI Express (mPCIe) interfaces and modern M.2 B key devices.

Operational Principle:
- The module receives input signals from the host system’s mPCIe slot.
- It routes and translates these signals to the M.2 B key connector, maintaining electrical compatibility for PCIe, USB 2.0, and SATA III interfaces.
- This allows the host system to communicate seamlessly with M.2 modules that use these protocols.

Use Cases and Applications:
- Embedded Systems: Enables integration of M.2 storage or communication modules into embedded boards that only provide mPCIe slots.
- Industrial PCs (IPCs): Expands upgrade options for industrial computers by supporting M.2 SSDs or wireless modules.
- IoT Gateways: Facilitates flexible module configuration in IoT edge devices.
- Networking Equipment: Allows installation of M.2 WWAN or LTE modules in routers or network appliances with mPCIe slots.
- System Prototyping and Testing: Useful for developers testing M.2 modules on platforms that only support mPCIe.

Compatibility:
- Compatible with M.2 B key modules supporting PCIe, SATA, or USB 2.0 interfaces.
- Works with standard mPCIe slots found in industrial motherboards, embedded systems, and single-board computers.
