The **MH61TAD-R** is a specialized industrial-grade motherboard, typically manufactured by companies like **Advantech** or **Fujitsu**, designed for high-reliability embedded applications. It follows the Mini-ITX form factor and is based on the Intel H61 chipset. --- ### Core Specifications Table | Feature | Specification | | :--- | :--- | | **Form Factor** | Mini-ITX (170 x 170 mm) | | **Chipset** | Intel® H61 Express | | **CPU Support** | Intel® 2nd/3rd Gen Core™ i7/i5/i3 (LGA1155) | | **Memory** | 2 x DDR3 SO-DIMM (Up to 16GB) | | **Graphics** | Integrated Intel HD Graphics (via CPU) | | **Storage** | 2 x SATA 2.0 (3 Gb/s) | | **Power Input** | 12V DC-In / ATX 4-pin | --- ### Key Electronic Components & Features #### 1. Chipset and Processor Architecture The heart of the board is the **Intel H61 PCH (Platform Controller Hub)**. This chipset acts as the communications hub for the CPU, managing data flow between the processor and peripheral devices. It supports the "Sandy Bridge" and "Ivy Bridge" architectures, which are known for their balance of power efficiency and processing speed in industrial controllers. #### 2. Power Delivery System Unlike standard consumer motherboards that use a 24-pin ATX connector, the "TAD" variant often features a **DC-In design**. * **Voltage Regulators:** High-quality Solid Capacitors are used to ensure stable voltage to the CPU (VRM - Voltage Regulator Modules). * **Input:** Usually accepts a 12V or 19V DC input, making it suitable for integration into kiosks or thin-profile industrial chassis. #### 3. Connectivity & I/O Interfaces The board is designed for legacy and modern industrial connectivity: * **Dual Display:** Usually equipped with VGA, DVI-D, or DisplayPort to support independent dual displays. * **Expansion:** Includes a **PCIe x16 slot** (for discrete graphics or high-speed I/O cards) and often a **Mini-PCIe slot** for Wi-Fi or mSATA modules. * **Networking:** Features high-performance Gigabit Ethernet controllers (often Intel or Realtek) for stable industrial networking. #### 4. Industrial Grade Reliability The "-R" suffix often denotes specific revisions or compliance (such as RoHS or specific industrial ruggedization). Key electronic traits include: * **Extended Life Cycle:** Components are selected for long-term availability (7+ years). * **Watchdog Timer:** A programmable electronic timer that can automatically reset the system if the software hangs, crucial for remote or unattended operation. --- ### Internal Connectors (Header List) 1. **COM Ports:** RS-232/422/485 headers for connecting to PLC or legacy industrial hardware. 2. **USB Headers:** Internal pins for additional USB 2.0 ports. 3. **LVDS Header:** For driving LCD panels directly without an external controller.
