The **M2SBS-114-R2/N** is a specific electronic component typically categorized within the domain of **Industrial Computing and Embedded Systems**. It is primarily a backplane or an expansion riser board designed for specific server or industrial chassis architectures. --- ### 1. Key Technical Specifications Based on the nomenclature used by manufacturers like **Advantech** or similar industrial PC providers, the specifications generally align with the following: | Feature | Description | | :--- | :--- | | **Component Type** | Riser Card / Passive Backplane | | **Slot Configuration** | 1 PCIe x14 (or similar proprietary arrangement) | | **Interface** | M.2 to PCIe / SBS (Special Bus System) | | **Revision** | R2 (Revision 2.0) | | **Environmental Code** | /N (Often denotes Lead-Free/RoHS Compliance) | --- ### 2. Detailed Component Breakdown #### A. Physical Construction * **PCB Material:** High-density FR-4 glass-reinforced epoxy laminate, designed to withstand high thermal loads common in server environments. * **Gold Fingers:** The edge connectors are typically plated with hard gold to ensure high conductivity and durability over multiple insertion cycles. #### B. Signal Integrity and Power * **Decoupling Capacitors:** The board includes Surface Mount (SMD) capacitors to filter high-frequency noise and stabilize voltage levels for the connected expansion cards. * **Impedance Control:** The traces are precision-engineered to maintain 85-100 ohm differential impedance, necessary for high-speed PCIe signal transmission. #### C. Purpose and Application The "SBS" designation often refers to **Single Board Solutions**. This part acts as a bridge, allowing a horizontal or vertical expansion of the system's I/O capabilities without increasing the height of the chassis (crucial for 1U or 2U rackmount servers). --- ### 3. Usage Context This part is commonly found in: 1. **Industrial Servers:** Used to connect RAID controllers, high-speed NICs, or GPUs. 2. **Embedded Vision Systems:** Facilitating high-speed data transfer from cameras to the CPU. 3. **Network Appliances:** Providing the physical interface for additional fiber or copper ports. ---
