The **W2PE-1ZE-R2/N** belongs to the high-performance computing hardware family, specifically associated with Advantech’s networking and server solutions. This part number refers to a specific configuration of an **Expansion Card/Riser Card** or an interface module designed for industrial server chassis. --- ### 🛠️ Technical Specifications & Role The "W2PE" series typically facilitates PCI Express (PCIe) expansion within 1U or 2U server environments where space is constrained. | Feature | Description | | :--- | :--- | | **Product Category** | Expansion Riser / Interface Module | | **Primary Interface** | PCIe x16 or x8 (Gen 3/Gen 4 compatibility) | | **Form Factor** | Low Profile / Proprietary Riser | | **Target Hardware** | Industrial Servers (SKY-series or ASMB-series) | | **Connector Type** | High-density gold finger connectors | --- ### 🔍 Key Electronic Components The board consists of several critical layers to ensure signal integrity and power stability: 1. **Multilayer PCB:** Uses high-frequency laminate materials (like Rogers or high-TG FR4) to minimize signal loss and electromagnetic interference (EMI) during high-speed data transfers. 2. **Impedance Control:** The traces are precision-etched to maintain 85-100 ohm differential impedance, critical for PCIe standards. 3. **Decoupling Capacitors:** Small Surface Mount Device (SMD) capacitors are placed near the power pins to filter out high-frequency noise and provide local energy storage. 4. **Signal Retimers/Redrivers (Optional):** Depending on the specific revision, these chips may be present to boost the PCIe signal over longer trace lengths. --- ### ⚠️ Usage Context This specific part is often found in **Network Video Recorders (NVR)** or **Edge AI Computing** nodes. Its primary function is to change the orientation of a peripheral card (like a GPU or a 10GbE NIC) from vertical to horizontal to fit into a slim rackmount chassis. --- ### 📝 Part Number Breakdown * **W2PE:** Series designation (often PCIe expansion). * **1ZE:** Specific mechanical/electrical configuration. * **R2:** Revision 2 (indicates a hardware update/bug fix from the original design). * **N:** Typically denotes "New" or a specific compliant lead-free manufacturing process. ---
