The **M2ADS-214-R2** is a specific electronic hardware component, typically categorized as a **High-Density Connector** or a **Mezzanine Card Interface**. These parts are frequently used in telecommunications, server infrastructure, and high-speed data transmission systems. --- ### 1. General Specifications While technical datasheets can vary by manufacturer (often associated with brands like Foxconn or specialized OEM suppliers), the "M2ADS" series generally follows these parameters: | Feature | Description | | :--- | :--- | | **Component Type** | Mezzanine Connector / Board-to-Board | | **Pin Count** | 214 Pins | | **Revision** | R2 (Indicates the second design iteration) | | **Mounting Type** | Surface Mount (SMT) | | **Application** | High-speed data links, PCIe expansion, or CPU/Memory modules | --- ### 2. Key Electronic Characteristics The electronic design of the M2ADS-214-R2 is centered around maintaining signal integrity at high frequencies. #### A. Signal Integrity and Shielding * **Differential Pairs:** The 214-pin layout is designed to support multiple differential pairs, which are essential for protocols like PCIe Gen 3/4 or 10GbE. * **Crosstalk Reduction:** The internal geometry of the pins is spaced to minimize electromagnetic interference (EMI) between adjacent data channels. #### B. Contact Material and Conductivity * **Plating:** Usually features Gold (Au) plating on the contact points to ensure low contact resistance and prevent oxidation over long periods. * **Current Rating:** Typically rated for 0.5A to 1.0A per pin, though it is primarily intended for signal rather than high-power delivery. #### C. Physical Geometry * **Pitch:** High-density connectors like this usually feature a fine pitch (often 0.5mm to 0.8mm). * **Standoff Height:** Designed to provide a specific "stacking height" between two printed circuit boards (PCBs). --- ### 3. Common Use Cases The M2ADS-214-R2 is most commonly found in: 1. **Blade Servers:** Connecting a daughter card to a motherboard. 2. **Networking Switches:** Interfacing high-speed optical modules with the main processing board. 3. **Industrial Computing:** Used in modular computers where the CPU resides on a separate module for easy upgrades. --- ### 4. Technical Precautions When working with this part, consider the following: * **Coplanarity:** Because it is an SMT part with 214 pins, the flatness of the PCB and the precision of the solder paste stencil are critical to avoid "open" joints. * **Mating Cycles:** These connectors usually have a rated life of 25 to 100 mating cycles. They are not intended for frequent plugging/unplugging like a USB port.
