What is a module?
The concept of module comes from modular programming paradigm which advocates that software should be composed of separate, interchangeable components called modules by breaking down program functions into modules, each of which accomplishes one function and contains everything necessary to accomplish this.
How do you determine the function of a board or module?
Reference the wiring diagram. Start by tracing the external wiring to determine the functions of the various inputs and outputs of the board, and to ascertain the power supply connections.
