The **M2CEC-2100B-R2** is a specific revision of a high-performance **Embedded Controller** (often referred to as a "Box PC") typically manufactured by Advantech or similar industrial computing brands. It is designed for industrial automation, machine vision, and IoT gateway applications. Below is a breakdown of its primary electronic components and specifications. --- ## 1. Core Computing Components The "brains" of the unit are designed for low power consumption but high stability. | Component | Description | | :--- | :--- | | **Processor (CPU)** | Usually features an **Intel Celeron J1900** (Quad Core, 2.0 GHz) or a similar Bay Trail/Apollo Lake processor. | | **Memory (RAM)** | Supports **DDR3L 1333/1600MHz** SO-DIMM slots, typically up to 8GB. | | **Chipset** | Integrated SoC (System on Chip) architecture for reduced heat and size. | --- ## 2. Storage & Expansion Interfaces Industrial units prioritize data integrity and modularity. * **Storage Slots:** * 1 x **mSATA** slot (Full-size) for SSDs. * 1 x **2.5" SATA HDD/SSD** bay for high-capacity storage. * **Expansion Slots:** * **Mini-PCIe:** Typically two slots (one full-size, one half-size) used for Wi-Fi, Bluetooth, or 4G LTE modules. * **SIM Card Slot:** Often integrated to support cellular connectivity. --- ## 3. Input/Output (I/O) Connectivity The electronic interface allows it to talk to factory machinery and sensors. ### Communication Ports * **Ethernet:** 2 x Gigabit LAN ports (usually Intel i210 or i211 controllers) supporting Wake-on-LAN. * **Serial Ports:** 2 to 4 x **COM ports** (RS-232/422/485), crucial for legacy industrial hardware. * **USB:** 1 x USB 3.0 and 3 x USB 2.0 ports. ### Display Outputs * **VGA:** Standard analog output. * **HDMI/DP:** Digital output for high-definition monitoring. --- ## 4. Power & Environmental Specs The electronic design accounts for "dirty" industrial power and harsh environments. * **Power Input:** 12V ~ 24V DC wide-range input (via terminal block or DC jack). * **Protection:** Integrated **Over-Voltage Protection (OVP)** and **Over-Current Protection (OCP)**. * **Cooling:** **Fanless design**—the aluminum chassis acts as a giant heatsink, preventing dust intake. --- ## 5. Typical Block Diagram Logic The internal electronics follow this data flow: ```mermaid graph LR Sensors --> COM_Ports COM_Ports --> CPU(Intel SoC) CPU --> RAM(DDR3L) CPU --> Storage(mSATA/SATA) CPU --> Network(GbE LAN) Network --> Cloud/Server ``` ---
