Embedded systems and Internet of Things (IoT) projects favor SMARC Modular for its benefits, including compact size, standardization, versatility, comprehensive processor/memory support, compatibility with OS, cost-effectiveness, and robustness. Measuring only 82mm x 50mm, they are an ideal option for projects with limited space. They also feature a standardized array of interfaces, including USB, Ethernet, serial, and display, allowing for compatibility and interchangeable use between modules from different manufacturers. The flexible expansion interface further supports additional interfaces such as PCI Express, SATA, and USB 3.0, allowing designers to customize to their specific needs. Support a wide range of processors and memory options, including x86, ARM, and RISC-based processors, as well as DDR3 and DDR4 memory. Additionally, they are compatible with various operating systems, such as Windows, Linux, and Android. Their cost-effectiveness stems from integrating the processing and memory components into a single module, reducing the need for additional details, and reducing development time and cost. The SMARC standard also outlines guidelines for environmental protection and EMC (Electromagnetic Compatibility) compliance, ensuring the modules are reliable for use in demanding applications. These features make SMARC an attractive option for embedded systems and IoT projects that require compact, scalable, and cost-effective solutions.
