The **M2AS1-A434-R2/N** is a specific part number typically associated with **M.2 (NGFF) SSD Adapters** or specialized carrier boards often found in embedded systems or IPC (Industrial PC) environments. Based on technical specifications for this series, here is the breakdown of the electronic parts and characteristics: ### 1. Component Overview The device serves as an interface bridge, allowing an M.2 module (usually a SATA or PCIe based SSD) to connect to a standard motherboard header or a proprietary slot. | Component Category | Description | | :--- | :--- | | **Form Factor** | M.2 (Next Generation Form Factor) | | **Connector Type** | M-Key or B+M Key (depending on specific revision) | | **PCB Layers** | High-density multi-layer FR4 PCB for signal integrity | | **Bus Interface** | Supports SATA III (6Gbps) or PCIe (NVMe) passthrough | | **Voltage** | Primary 3.3V operation via M.2 rail | --- ### 2. Key Electronic Features * **Voltage Regulation:** The board contains surface-mount (SMD) capacitors (typically MLCC) to filter noise and stabilize the 3.3V power delivery to the SSD controller. * **Signal Routing:** Uses differential pair routing with controlled impedance (usually 85Ω or 100Ω) to ensure high-speed data transfer without data corruption. * **Gold Finger Contacts:** The edge connector features 30μ" gold plating to prevent oxidation and ensure low-resistance connectivity over multiple insert/extract cycles. * **LED Indicators:** Often includes a small SMD LED to indicate "Power Good" or "Drive Activity" (ACT). --- ### 3. Technical Specifications Table | Specification | Details | | :--- | :--- | | **Interface** | M.2 to SATA / PCIe Carrier | | **Supported Lengths** | 2242, 2260, 2280 (standard mounting holes) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Retention** | Screw-down standoff for secure vibration resistance | | **RoHS Status** | Compliant (Lead-Free) | --- ### 4. Typical Application Circuitry In these modules, the "electronic parts" are mostly passive or protective: 1. **Decoupling Capacitors:** Prevent voltage drops during high-speed NAND flash operations. 2. **Zero-Ohm Resistors/Jumpers:** Used for configuration settings or as fuses for over-current protection. 3. **EEPROM (Optional):** Some versions may include a small IC to store board ID information for BIOS/UEFI recognition.
