The **M2SES2-AB-R2/CE** is a high-performance, industrial-grade **Single Board Computer (SBC)** or System-on-Module (SoM) based on the ARM architecture. This specific model is part of the M2SES series, often utilized in embedded systems requiring high reliability and specific industrial certifications (CE). --- ### 1. Core Electronic Specifications The board is designed for embedded computing, featuring a balance between processing power and low energy consumption. | Component | Specification Details | | :--- | :--- | | **Processor (CPU)** | Usually features an ARM Cortex-A series (often A7 or A9 depending on the specific revision). | | **Memory (RAM)** | Typically 512MB to 1GB DDR3 RAM. | | **Storage** | Integrated eMMC (4GB to 8GB) and a MicroSD slot for expandable storage. | | **Input Voltage** | 5V DC (standard industrial regulated input). | | **Operating Temp** | Industrial grade: -40°C to +85°C. | --- ### 2. Connectivity and Interfaces The "AB" and "R2" designations often refer to the revision and the specific I/O breakout available on the PCB. * **Networking:** 10/100/1000 Mbps Ethernet port (RJ45). * **USB Ports:** Multiple USB 2.0 Host ports and one USB OTG (On-The-Go) for programming. * **Serial Communication:** Support for RS-232, RS-485, and CAN bus (essential for industrial automation). * **Display Output:** LVDS or RGB interface for connecting industrial LCD panels. * **Expansion:** GPIO pins, I2C, and SPI headers for connecting sensors or custom daughterboards. --- ### 3. Key Design Features The **R2/CE** suffix indicates specific hardware standards: 1. **R2 (Revision 2):** Refers to the second generation of the hardware layout, usually involving improved power management circuits or better EMI (Electromagnetic Interference) shielding over the original version. 2. **CE Certification:** The "CE" mark indicates the electronics comply with European health, safety, and environmental protection standards, specifically regarding electrical noise and safety. 3. **Form Factor:** Compact design, often following the M.2 or similar standardized module dimensions for easy integration into larger carrier boards. --- ### 4. Typical Applications Because of its rugged nature, this part is commonly found in: * **Industrial HMI:** Human-Machine Interfaces for factory floor control. * **IoT Gateways:** Collecting data from local sensors and uploading it to the cloud. * **Medical Devices:** Reliable processing for diagnostic equipment. * **Vending/Kiosks:** Driving displays and handling payment peripherals. ---
