The **M2PE-14-R/N** is a specific part number typically associated with high-performance **M.2 (NGFF) connectors** or related testing/interface hardware used in telecommunications and data processing environments. Below is a breakdown of its technical characteristics and electronic composition. --- ### 1. General Specifications The part belongs to the **M.2 (Next Generation Form Factor)** family, designed to replace mSATA. It is primarily used for SSDs, Wi-Fi modules, and LTE/5G cellular cards. | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (NGFF) Socket | | **Interface Speed** | Supports PCIe Gen 3/4, SATA 3.0, and USB 3.0 | | **Orientation** | Right-Angle / Horizontal (indicated by 'R') | | **Pin Count** | 67-75 Positions (Standard M.2) | | **Pitch** | 0.50 mm | --- ### 2. Key Electronic Components & Design The internal architecture of this part is engineered for high-frequency signal integrity. * **Contact Material:** Usually a copper alloy with gold plating (often 15µ" or 30µ") on the contact area to prevent oxidation and ensure low contact resistance over multiple mating cycles. * **Housing:** High-temperature Liquid Crystal Polymer (LCP) or Thermoplastic, rated for lead-free reflow soldering (capable of withstanding ~260°C). * **Keying (The "N" Suffix):** In many M.2 naming conventions, the suffix indicates the "Key" (e.g., Key B, Key M, or Key E). This prevents the wrong type of card from being inserted into the socket. --- ### 3. Pinout and Signal Distribution While the specific pinout depends on the assigned "Key," a standard M.2 connector like the M2PE series follows this general electronic layout: | Pin Groups | Function | | :--- | :--- | | **Power Rails** | 3.3V supply to the module. | | **Differential Pairs** | High-speed data lanes (PETp/n, PERp/n) for PCIe communication. | | **Control Signals** | Reset (PERST#), Clock Request (CLKREQ#), and Wake (WAKE#). | | **Ground (GND)** | Extensive grounding to shield differential pairs and reduce EMI (Electromagnetic Interference). | --- ### 4. Application Use Cases This part is commonly found in: 1. **Industrial Embedded PCs:** For adding NVMe storage in compact spaces. 2. **Network Appliances:** Integrating 4G/5G modems. 3. **Development Boards:** Used by engineers to prototype high-speed data transfer modules. --- ### 5. Mechanical Integration The "R" in the part number often denotes **Right Angle**, meaning the M.2 card sits parallel to the PCB (Motherboard) to save vertical space. ```yaml Mounting: Surface Mount (SMT) Retention: Solder pegs for mechanical stability Height: Low profile (typically 2.0mm to 4.5mm) ```
