The **M2PE-1E-R/N** is a specialized electronic component, typically classified as a **High-Speed Signal Connector** or an **Interface Module**, often used in industrial computing and storage expansion (such as M.2 to PCIe conversions). Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Category** | Interface Bridge / Expansion Connector | | **Interface Type** | M.2 (Key E) to PCI Express | | **Signal Lanes** | 1-Lane (x1) PCIe Support | | **Voltage Input** | 3.3V (Typical for M.2 slots) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | ### 2. Electronic Architecture The "M2PE" series focuses on adapting the **M.2 form factor** to standard PC architecture. Here are the core electronic parts involved: * **Signal Integrity Circuitry:** Includes differential pair routing designed to maintain the 8 GT/s (Gigatransfers per second) required for PCIe Gen 3.0. * **Power Management (LDO/Regulators):** Often contains Low-Dropout Regulators to convert the host 3.3V rail into stable voltages for specific Wi-Fi, Bluetooth, or IoT modules. * **Pin Configuration:** * **Key E:** Specifically designed for Wireless connectivity (Wi-Fi/BT/NFC). * **Pins 1-75:** Standardized mapping for PCIe x1, USB 2.0, and I2C signals. ### 3. Part Number Decoder (Typical) Electronic manufacturers use suffixes to denote specific build configurations: * **M2PE:** M.2 to PCIe Series. * **1E:** Indicates 1-Lane PCIe capability and Key E physical slotting. * **R/N:** * **R:** Often stands for **RoHS Compliant** or **Reversed** orientation. * **N:** Usually indicates **Non-isolated** or specific mounting hardware (Nut/Screw) inclusion. ### 4. Application Use Cases 1. **Industrial PCs:** Adding Wi-Fi 6 or Bluetooth modules to motherboards lacking integrated wireless. 2. **Embedded Systems:** Connecting AI accelerators (like Coral M.2) to small-form-factor boards. 3. **Prototyping:** Testing M.2 modules on standard PCIe testing jigs. --- ### 5. Technical Precautions ```markdown * Ensure the host M.2 slot supports "Key E". A "Key M" (SSD) slot is physically incompatible. * Check the BIOS/UEFI settings to ensure the PCIe lane bifurcation is set correctly if using multiple adapters. * Monitor thermal output; high-speed signal adapters can generate localized heat during heavy data transfers. ```
