The **M3A72FBX-R** is an industrial-grade motherboard typically associated with NEXCOM. It is designed for reliability in harsh environments, often used in digital signage, automation, or network appliances. Below is a breakdown of its primary electronic components and specifications: ### 1. Core Processing & Chipset The board is built on a specific architecture designed for balancing power consumption and performance. | Component | Specification | | :--- | :--- | | **CPU Support** | AMD Turion™ 64 X2 / Athlon™ 64 X2 / Sempron™ (Socket S1) | | **Northbridge** | AMD RS780E | | **Southbridge** | AMD SB710 | | **FSB/HT** | HyperTransport 3.0 support | --- ### 2. Memory & Storage Interface The electronic layout prioritizes stable data throughput via standard industrial interfaces. * **RAM Slots:** 2 x 200-pin DDR2 SO-DIMM sockets. * **Max Capacity:** Supports up to 4GB of DDR2 667/800 MHz. * **SATA:** 2 x SATA II (3.0 Gb/s) connectors for HDD/SSD. * **CF Socket:** Often includes a CompactFlash Type I/II socket for OS redundancy or embedded storage. --- ### 3. I/O Connectivity & Controllers The "FBX" series usually features a rich array of I/O for peripheral communication. | Interface | Type/Controller | | :--- | :--- | | **Ethernet** | Dual Realtek RTL8111C Gigabit LAN controllers | | **USB** | 4 to 6 USB 2.0 ports (Rear + Internal Headers) | | **Serial (COM)** | Multiple RS232 headers (Essential for industrial sensors) | | **Video Output** | Integrated ATI Radeon™ HD 3200 (VGA/DVI/HDMI options) | | **Audio** | Realtek ALC888 High Definition Audio | --- ### 4. Expansion and Power The board's physical layout is designed to fit into specific chassis (like the NDiS series). * **PCIe Expansion:** Usually features 1 x PCIe x16 slot for dedicated graphics or high-speed I/O cards. * **Power Input:** Typically requires a 12V DC input or a standard ATX power header depending on the specific revision. * **Watchdog Timer:** Integrated hardware timer to reset the system if software hangs (critical for remote deployments). --- ### 5. Technical Identification (BIOS/Firmware) If you are troubleshooting the board, the BIOS string often identifies the manufacturing date and specific revision: ```text Project Name: M3A72FBX BIOS Provider: AMI (American Megatrends Inc.) Core Version: 08.00.15 ``` ---
