The **M2AS1-A213-R** is a specific model of an **M.2 to SATA Adapter/Converter**. These devices are used to bridge the interface between an M.2 (NGFF) form factor SSD and a standard SATA interface, typically for use in legacy laptops, desktops, or external enclosures. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Model** | M2AS1-A213-R | | **Primary Interface** | M.2 (NGFF) Key B or B+M | | **Output Interface** | 7+15 Pin SATA III (6Gbps) | | **Supported Sizes** | 2230, 2242, 2260, 2280 | | **Voltage Input** | 3.3V (via SATA power) | | **Protocol Support** | **SATA-based M.2 ONLY** (Does not support NVMe/PCIe) | --- ### Key Electronic Components The "electronic parts" of this adapter are relatively simple but critical for data integrity and power management: #### 1. The PCB (Printed Circuit Board) The board serves as the physical mounting point. It contains traces that map the tiny pins of the M.2 connector directly to the larger pins of the SATA connector. Since SATA-based M.2 drives use the same protocol as standard SATA drives, there is usually **no controller chip** required (it is a passive bridge). #### 2. Power Regulation (LDO/Voltage Buck) * **Voltage Step-down:** SSDs typically operate on 3.3V. Standard SATA power connectors provide 5V and 12V. * **Capacitors:** You will see small SMD (Surface Mount Device) capacitors on the board. These act as filters to smooth out electrical noise and provide a small reserve of power to prevent data loss during minor voltage ripples. #### 3. Connectors * **M.2 Slot:** A 75-position connector. * **SATA Connector:** A standard 22-pin (Data + Power) gold-plated connector. #### 4. Mounting Hardware The "-R" in the model often signifies a specific revision or a retail package that includes a screw-down standoff to secure the M.2 card at various lengths (42mm, 60mm, or 80mm). --- ### Important Compatibility Note > [!CAUTION] > This adapter is designed for **SATA M.2 SSDs**. It will not work with **NVMe (M-Key)** drives. If you plug an NVMe drive into this adapter, the computer will not recognize the drive because the SATA protocol cannot communicate with the PCIe protocol used by NVMe. ---
