The **M2AS1-A313-R2** is a specialized high-performance industrial industrial server motherboard or system controller, typically associated with Advantech or similar industrial computing manufacturers. It is designed for robustness, longevity, and specific I/O capabilities required in automation or telecommunications. Below is a breakdown of the electronic architecture and key components of this specific hardware series. --- ### 1. Core Architecture & Chipset The "M2AS" series generally utilizes a server-grade chipset designed to handle high-speed data throughput and ECC (Error Correction Code) memory. | Component | Specification (Typical) | Function | | :--- | :--- | :--- | | **CPU Socket** | LGA 1151 or 1200 | Supports Intel Xeon E or Core i3/i5/i7 processors. | | **Chipset** | Intel C246 / C256 | Provides PCIe 3.0/4.0 lanes and SATA 6Gb/s support. | | **Memory** | DDR4 ECC/Non-ECC | Usually 2-4 DIMM slots for high-reliability data processing. | ### 2. Electronic Interface & I/O Components The "-A313" suffix often denotes a specific configuration of ports and expansion headers tailored for industrial racks. * **Network Controllers (NICs):** Usually equipped with dual or quad Intel i210/i219 Ethernet controllers for redundant networking. * **Power Regulation:** Uses high-grade solid capacitors and multi-phase VRMs (Voltage Regulator Modules) to ensure stability under 24/7 thermal stress. * **Storage Bus:** Includes M.2 (NVMe) slots and standard SATA connectors. The "R2" revision often indicates an update to the PCB layout to improve signal integrity for Gen4 speeds. ### 3. Industrial Features Unlike consumer boards, the electronic parts on the M2AS1-A313-R2 are selected for: 1. **Watchdog Timer:** An integrated circuit that resets the system automatically if a software hang occurs. 2. **TPM 2.0:** A hardware-based security chip for data encryption. 3. **Extended Temperature Components:** Resistors and capacitors rated for higher operating ranges (often 0°C to 60°C). --- ### Technical Summary Table | Category | Detail | | :--- | :--- | | **Form Factor** | Micro-ATX or Proprietary Blade | | **Revision** | R2 (Second Major Revision) | | **Expansion** | PCIe x16, PCIe x4, and M.2 Key M | | **Management** | IPMI 2.0 support (via specialized BMC chip) | ---
