Based on the product code provided, this part refers to an **M.2 (NGFF) to SATA Adapter/Converter Card**, typically associated with industrial or commercial storage expansion solutions. Below is a detailed breakdown of its electronic components and specifications. --- ### 1. Component Overview This device is designed to interface an **M.2 SATA-based SSD** with a standard **7+15 Pin SATA** connection. | Feature | Specification | | :--- | :--- | | **Interface Type** | M.2 (Key B or B+M) to SATA III | | **Data Rate** | Up to 6Gbps (SATA III standards) | | **Form Factor** | Supports 2230, 2242, 2260, and 2280 M.2 lengths | | **Voltage Input** | 3.3V (derived from the 5V SATA power rail) | | **Connector A** | M.2 NGFF M-Key / B-Key Slot | | **Connector B** | Standard SATA 22-pin (Power + Data) | --- ### 2. Key Electronic Features #### A. Power Management (Voltage Regulation) Since M.2 SSDs operate on **3.3V** and standard SATA power cables provide **5V/12V**, the board contains a **Step-down Voltage Regulator (Buck Converter)** or a High-current LDO (Low Dropout Regulator). This ensures the SSD receives a stable 3.3V supply. #### B. Signal Integrity (Passive Pass-through) Unlike NVMe adapters which require active PCIe bridges, this is primarily a **passive signal router**. - It maps the differential pairs of the M.2 SATA pins directly to the SATA connector pins. - It includes **Decoupling Capacitors** (usually MLCC) to filter high-frequency noise and ensure stable data transmission. #### C. Safety Components * **TVS Diodes:** Often included to protect the SSD from electrostatic discharge (ESD) during installation. * **LED Indicators:** Usually features a Power LED (Solid) and an Activity LED (Blinking during data transfer). --- ### 3. Pin Mapping Logic The adapter electronically bridges the following pins: | M.2 Pin | Signal Name | SATA Equivalent | | :--- | :--- | :--- | | **Pin 41-49** | SATA-B / SATA-A (Diff pairs) | SATA Data TX/RX | | **Pin 2-4** | 3.3V Power | SATA Power (after 5V conversion) | | **Pin 1-11** | GND | Common Ground | --- ### 4. Compatibility Note > **Critical:** This electronic part **does not support NVMe (PCIe) SSDs**. It only functions with M.2 modules that use the SATA protocol. If an NVMe drive is inserted, it will not be recognized because the electronic traces are mapped for SATA differential signaling only. ---
