The **M2AS1-5142-R2/N** is a specific electronic component typically identified as an **M.2 (NGFF) Connector**. These connectors are widely used in modern computing to interface SSDs (Solid State Drives), Wi-Fi cards, and Bluetooth modules with motherboards or embedded systems. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (Next Generation Form Factor - NGFF) | | **Pitch** | 0.50 mm | | **Number of Pins** | 67 Pins | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Keying** | Usually "M" or "B" Key (Check specific datasheet for this revision) | | **Height** | 4.2mm (Commonly denoted by the '42' in the suffix) | | **Housing Material** | High-Temperature Thermoplastic (UL94V-0) | --- ### 2. Physical Design & Composition The part is engineered for high-density environments where vertical space is limited. * **Contacts:** Usually made of Copper Alloy with Gold plating over Nickel. Gold is used to ensure high conductivity and prevent oxidation over long periods. * **Solder Tabs:** Features metal "ears" or solder tabs on the sides to provide mechanical strain relief, ensuring the connector doesn't lift off the PCB during the insertion/removal of the M.2 card. * **Orientation:** This is a **horizontal (right-angle)** connector, meaning the M.2 card sits parallel to the PCB once inserted. --- ### 3. Electrical Performance Designed to handle high-speed data protocols including PCIe Gen 3/4, SATA 3.0, and USB 3.0. * **Current Rating:** Typically 0.5A per pin. * **Voltage Rating:** 50V AC/DC. * **Insulation Resistance:** 500MΩ minimum. * **Operating Temperature:** -40°C to +85°C. --- ### 4. Application Use Cases This component is found in various hardware categories: 1. **Laptops/Ultrabooks:** Interfacing NVMe SSDs to the mainboard. 2. **Industrial PCs:** Providing modular expansion for storage or wireless communication. 3. **IoT Gateways:** Used for pluggable WAN modules (LTE/5G). 4. **Single Board Computers (SBCs):** Adding high-speed storage capabilities to ARM or x86 boards. ---
