The **SBS-C2-R/Q** refers to a high-performance, single-board computer (SBC) module, typically associated with the **SBS** (Smart Battery System) or **VME/CompactPCI** industrial standards, often manufactured by companies like GE Intelligent Platforms (now Abaco Systems). Below is an overview of its electronic components and architecture. --- ### 1. Core Processing Unit The heart of the module is designed for rugged, high-reliability computing tasks. | Component | Description | | :--- | :--- | | **CPU Architecture** | Typically features an Intel Core 2 Duo or similar x86 architecture. | | **Clock Speed** | Generally ranges from 1.5GHz to 2.2GHz depending on the specific "R" or "Q" sub-revision. | | **L2 Cache** | Shared cache (2MB - 4MB) to reduce memory latency for high-speed calculations. | --- ### 2. Memory and Storage The board utilizes specialized memory modules to handle extreme temperatures and vibrations. * **RAM (System Memory):** Usually equipped with 1GB to 4GB of DDR2 or DDR3 SDRAM with **ECC (Error Correction Code)** support. This is critical for preventing data corruption in aerospace or industrial environments. * **Flash Storage:** Integrated soldered NAND Flash (CompactFlash or mSATA) used for OS hosting (VxWorks, Linux, or Windows Embedded). * **NVRAM:** Non-volatile RAM for storing critical system parameters and error logs during power loss. --- ### 3. Connectivity and I/O Interfaces The "C2" series is known for its high-density I/O capabilities. * **Ethernet:** Dual or Quad Gigabit Ethernet ports (10/100/1000Base-T). * **Serial Ports:** RS-232/422/485 interfaces for legacy industrial equipment communication. * **USB:** USB 2.0 ports for peripheral interfacing. * **PMC/XMC Slots:** Expansion slots that allow for mezzanine cards (like specialized FPGA or Analog-to-Digital converters) to be added to the base board. --- ### 4. Technical Specifications Summary | Feature | Specification Details | | :--- | :--- | | **Form Factor** | 3U or 6U VME / CompactPCI | | **Cooling** | Available in Air-cooled (R) or Conduction-cooled (Q) versions | | **Power Consumption** | Typically 25W - 45W depending on load | | **Operating Temp** | -40°C to +85°C (Ruggedized versions) | --- ### 5. Ruggedization Variants (R vs. Q) The suffix in the part number usually denotes the environmental sealing and cooling method: 1. **R (Ruggedized Air-Cooled):** Uses fans and heat sinks for heat dissipation in controlled environments. 2. **Q (Conduction-Cooled):** Heat is dissipated through a thermal frame to the chassis, used in sealed, fanless, or high-altitude environments.
