These are not the core computing modules, but rather the supportive eLEMents that may provide additional connectivity, power management, signal conditioning, or mounting solutions. The main functions of accessories can range from simplifying the development process, like extension boards or adapters, to providing necessary operational components such as heat sinks, power supplies, and cable harnesses.
The main uses of accessories are to ensure that embedded computers can be easily integrated into a wider system, to customize the computer for specific applications, or to replace worn-out or outdated parts. Characteristics of these products include their ability to meet industry standards for compatibility, reliability, and durability. Accessories are designed to be user-friendly, often enabling plug-and-play functionality. Several manufacturers of accessories for embedded computers include Adafruit Industries, SparkFun Electronics, and Digi-Key Electronics.
