The **M2XUM-00-R** is a specific electronic component within the **M2X series**, manufactured by **Advantech**. It is primarily designed as a modular expansion card used in industrial computing and networking applications. --- ### 1. Component Overview The M2XUM-00-R is a **Mini PCIe to USB 3.0** expansion module. Its primary function is to convert an internal Mini PCI Express slot into high-speed USB ports, typically for industrial PCs (IPCs) or embedded systems that require additional peripheral connectivity. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Form Factor** | Full-size Mini PCIe | | **Interface** | PCI Express Gen 2 x1 | | **Output Ports** | 2 x USB 3.0 Ports | | **Data Transfer Rate** | Up to 5 Gbps (SuperSpeed) | | **Power Output** | 5V / 900mA per port | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Controller** | Renesas uPD720202 (commonly used) | --- ### 3. Key Electronic Features #### A. High-Speed Connectivity By leveraging the **PCI Express Gen 2** bus, the module bypasses the limitations of legacy USB 2.0 headers, allowing for the full bandwidth (5 Gbps) required by industrial cameras, high-speed sensors, and external storage. #### B. Power Management Because the Mini PCIe slot itself provides limited power (3.3V), the M2XUM-00-R often features a **DC-to-DC converter** or an external 4-pin/SATA power connector requirement to ensure each USB 3.0 port receives a stable **5V/900mA** output as per USB standards. #### C. Ruggedized Design The "-R" in the part number often signifies a ruggedized or revised version suitable for **wide-temperature** environments. This includes: * Solid-state capacitors for longevity. * Industrial-grade PCB coating. * High-tolerance oscillators. ### 4. Typical Applications * **Industrial Automation:** Connecting high-resolution vision cameras to a compact IPC. * **IoT Gateways:** Adding LTE or Wi-Fi dongles that require USB 3.0 bandwidth. * **Embedded Systems:** Expanding I/O in space-constrained enclosures where standard PC expansions aren't possible. --- ### 5. Installation Note To utilize this part, the host motherboard must have a **Full-size Mini PCIe slot** with a PCIe signal. Note that some Mini PCIe slots are "mSATA only" and will not support this module.
