What does the Commander Site Controller primarily use for its processing capabilities?

The Commander Site Controller primarily utilizes a Single Board Computer for its processing capabilities. A Single Board Computer is an integrated system that houses all the necessary components of a computer on a single circuit board. This design allows for efficient processing, compactness, and lower power consumption, making it ideal for environments where space and energy efficiency are critical.

The use of a Single Board Computer in the Commander Site Controller means it can effectively handle local processing tasks, such as transaction processing, network management, and communications with other devices on site. This local processing capability enhances performance and reliability since it can manage tasks without relying heavily on external servers, reducing latency and dependency on network conditions.

While the other options have their uses, they do not align as closely with the specific requirements and functionalities of the Commander Site Controller. For instance, a microcontroller typically handles simpler tasks and may not provide the necessary processing power and flexibility needed for the complex operations of a site controller. Cloud servers would involve external dependencies and latency that a site controller may want to avoid for immediate processing tasks. A remote CPU, while capable of processing, may not be as integrated or efficient as a Single Board Computer in a localized setup.
