The **M2PV-C1SB-R2** is an internal model designation typically used by **ORICO** for their M.2 NVMe SSD Enclosures. This specific model is a high-performance external storage solution that bridges the gap between internal NVMe storage and external USB interfaces. --- ## 1. Core Electronic Components The functionality of the M2PV-C1SB-R2 relies on several critical electronic sub-systems: | Component | Function | Detail | | :--- | :--- | :--- | | **Bridge Controller** | Realtek RTL9210 | Converts PCIe NVMe signals to USB 3.1 Gen2 protocols. | | **Interface Port** | USB Type-C | Supports data transfer rates up to 10Gbps. | | **PCB Layout** | Multi-layer FR4 | Designed for high-frequency signal integrity and heat dissipation. | | **Voltage Regulator** | Buck Converter | Steps down 5V (USB) to 3.3V (standard for M.2 SSDs). | | **Thermal Pad** | Passive Cooling | Conducts heat from the SSD controller to the aluminum alloy shell. | --- ## 2. Technical Specifications Below are the electronic specifications and limitations of the device: ### Connectivity & Power - **Input Interface:** USB 3.1 Gen2 Type-C. - **Max Bandwidth:** 10 Gbps (Theoretical speed ~1000MB/s). - **Power Delivery:** Bus-powered via USB (Requires ~5V/0.9A to 5V/1.5A depending on the SSD). ### Supported SSD Types - **Protocol:** NVMe (PCIe-based). *Note: Does not support SATA/NGFF protocol.* - **Form Factors:** 2230, 2242, 2260, and 2280. - **Key Type:** M-Key or B+M Key. --- ## 3. Circuit Design Highlights 1. **The RTL9210 Chipset:** This is the "brain" of the device. It is favored in high-end enclosures because it features a low-temperature operation profile and includes a built-in mechanism to prevent data corruption during accidental disconnects. 2. **ESD Protection:** The PCB usually includes TVS (Transient Voltage Suppressor) diodes near the Type-C port to protect the internal circuitry from static electricity when plugging/unplugging. 3. **LED Indicator:** A surface-mount LED is integrated into the circuit to indicate power status (solid) and data activity (blinking). --- ## 4.
