The **M2AS1-5121-R** is a specific part number typically associated with high-speed, high-density connectors used in industrial and computing applications. While specific "house" part numbers can sometimes vary by manufacturer, this specific nomenclature is most commonly linked to **M.2 (NGFF) connectors** or high-speed board-to-board interfaces. ### 1. General Specifications The following table outlines the technical characteristics typically found in this series of components: | Parameter | Specification | | :--- | :--- | | **Connector Type** | M.2 (Next Generation Form Factor - NGFF) | | **Mounting Type** | Surface Mount (SMT) | | **Orientation** | Right Angle / Horizontal | | **Pin Count** | 67-Pin / 75-Position (standard for M.2) | | **Pitch** | 0.50 mm | | **Height** | 2.1mm to 4.2mm (Depending on "1-5121" variant) | | **Keying** | Usually B-Key or M-Key (check specific datasheet) | --- ### 2. Key Electronic Features * **High-Speed Signal Integrity:** Designed to support PCIe Gen 3/Gen 4, SATA 3.0, and USB 3.0 protocols. * **Gold Plating:** The contact points are usually plated with gold (often 10u" to 30u") to prevent oxidation and ensure low contact resistance over time. * **Grounding Pegs:** Often includes metal "ears" or solder tabs on the sides to provide mechanical stability and a chassis ground path. * **Low Profile:** The "1-5121" suffix often indicates a specific height (e.g., 2.1mm) designed for slim laptops, tablets, or embedded IoT devices. --- ### 3. Pinout Structure (Standard M.2) While the exact pinout depends on the "Key" (A, B, E, or M), a standard M.2 connector like this generally follows this power/data distribution: ```yaml Standard Pin Groups: - Pins 1-11: Ground and Voltage (3.3V) - Pins 12-19: Specific Interface (USB/PCIe/SATA) - Pins 20-69: High-speed differential pairs (TX/RX) - Pins 70-75: Power and Ground ``` --- ### 4. Typical Applications 1. **Storage:** Connecting NVMe or SATA SSDs to a motherboard. 2. **Connectivity:** Housing Wi-Fi 6/7 or Bluetooth modules. 3. **Industrial PCs:** Compact expansion slots for AI accelerators or cellular (4G/5G) modems. ---
