The **ME11XBA-R** is an industrial-grade mainboard (motherboard) developed by **MiTAC**. It is designed for embedded systems, point-of-sale (POS) terminals, and thin-client applications. It belongs to the "Thin Mini-ITX" form factor category, characterized by its low-profile design. --- ### 1. Core Technical Specifications The board is built around the **Intel® Apollo Lake** platform, which emphasizes power efficiency and fanless operation. | Component | Specification Details | | :--- | :--- | | **Processor (SoC)** | Intel® Celeron® N3350 (Dual Core) or N3450 (Quad Core) | | **Form Factor** | Thin Mini-ITX (170mm x 170mm) | | **Memory** | 2 x DDR3L 1866MHz SO-DIMM slots (Up to 8GB) | | **Graphics** | Intel® HD Graphics 500/505 | | **Storage** | 1 x SATA III (6.0 Gb/s) & 1 x M.2 (Key M) | | **Power Input** | DC-in 12V / 19V (External adapter or internal header) | --- ### 2. Connectivity and Expansion Ports The "R" in the model name often signifies specific revisions or internal configurations optimized for industrial I/O (Input/Output). #### Internal Headers: * **Expansion:** 1 x M.2 Key E (for WiFi/BT modules). * **Serial Ports:** Often includes headers for up to 4x COM ports (RS232/422/485). * **USB:** Internal headers for USB 2.0. * **Display:** LVDS or eDP (Embedded DisplayPort) for driving internal LCD panels. #### Rear I/O Panel: * **Display Output:** HDMI and DisplayPort (supports dual independent displays). * **USB:** 4 x USB 3.0 Type-A ports. * **LAN:** Dual Gigabit Ethernet (Intel® i211AT or similar) for network redundancy. * **Audio:** Line-out and Mic-in jacks. --- ### 3. Key Electronic Characteristics * **Wide Voltage Design:** Supports a flexible DC input range (typically 12V to 19V), making it compatible with various power supplies. * **Thermal Design:** Engineered for **Passive Cooling**. The SoC has a very low TDP (Thermal Design Power) of 6W, allowing the system to run without a noisy mechanical fan. * **High Reliability:** Uses solid capacitors and industrial-grade controllers to ensure 24/7 operation in harsh environments. * **Watchdog Timer:** Includes a programmable timer that can automatically reboot the system if the software hangs. --- ### 4. Typical Use Cases Due to its thin profile and low power consumption, the ME11XBA-R is commonly found in: 1. **Digital Signage:** Driving high-definition displays in public spaces. 2. **Kiosks:** Integrated into self-service machines. 3. **Industrial Automation:** Acting as a controller for factory floor equipment. 4. **Medical Devices:** Used in low-noise diagnostic equipment.
