The **M2ADS-E14-R2** is a specific model of an **M.2 to Dual SATA Adapter**. This electronic component is designed to expand storage capabilities by converting an M.2 (NGFF) slot into two standard SATA 6Gbps ports. Below is a detailed breakdown of its electronic components and specifications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Interface (Host)** | M.2 Key B or Key B+M | | **Interface (Device)** | 2 x SATA 7-pin connectors | | **Data Rate** | SATA III (up to 6.0 Gbps) | | **Form Factor** | M.2 2242 / 2260 / 2280 (Breakable PCB) | | **Controller IC** | Typically ASMedia ASM1061 or JMicron JMB582 | | **Protocol** | AHCI (Plug and Play) | --- ### 2. Primary Electronic Components The PCB (Printed Circuit Board) houses several critical parts that facilitate data translation and power management: #### A. The Bridge Controller (The Brain) The most critical part is the **PCI Express to SATA Bridge**. * **Function:** It converts the PCIe lanes provided by the M.2 slot into SATA signals. * **Performance:** These chips support Native Command Queuing (NCQ) and Port Multipliers. #### B. Voltage Regulators (LDOs) M.2 slots provide 3.3V, while SATA logic often requires specific stability. * **Function:** Low-Dropout (LDO) regulators step down or stabilize the voltage to ensure the controller chip doesn't overheat or malfunction during high-speed data transfers. #### C. Quartz Crystal Oscillator * **Function:** A small metallic component (usually 20MHz or 25MHz) that provides the precise clock signal required for synchronized data transmission between the motherboard and the hard drives. #### D. Protection Circuits (Capacitors & Resistors) * **SMD Capacitors:** Used for decoupling to filter out electronic noise from the power supply. * **Termination Resistors:** Ensure signal integrity across the high-speed data lines to prevent data corruption. --- ### 3. Physical Layout and Connectivity 1. **M.2 Gold Fingers:** The contact points that slide into the motherboard. These carry both the PCIe data signals and the 3.3V power. 2. **SATA Connectors:** Two standard 7-pin data headers. *Note: These do not provide power to the drives; external SATA power cables from the PSU are still required.* 3. **LED Indicators:** Most R2 versions include tiny SMD LEDs to indicate "Power" (Solid) and "Activity" (Blinking). --- ### 4. Hardware Installation Requirements To use this electronic part effectively, the following conditions must be met: * **Slot Compatibility:** The M.2 slot on the motherboard must support **PCIe signaling**. If the slot is "SATA-only M.2," this adapter will not function. * **Driver Support:** Since it uses the standard AHCI protocol, it is natively supported by Windows 8/10/11, Linux, and macOS without needing manual driver installation. ---
