Embedded boards integrate microcontrollers with additional hardware and interfaces to make development easier.
Detailed Explanation
Embedded boards are platforms that combine microcontrollers—small, dedicated computing devices designed for specific tasks—with extra hardware and interfaces such as sensors, displays, and communication modules. This integration allows developers to more easily create and test their IoT applications, as they don't need to build everything from the ground up. Embedded boards usually come with a variety of features that enhance ease of use.
Examples & Analogies
Think of an embedded board like a Swiss Army knife. Just as a Swiss Army knife combines multiple tools—scissors, a screwdriver, and a bottle opener—into one compact device, an embedded board combines a microcontroller with various components and connectors, making it easier to tackle different tasks without needing separate devices.
