Product Details Data Sheet

Computer board alias computer control board, control module, circuit control board, electric control board, refers to the core components of the computer controller, usually composed of hardware and software, used for large-scale equipment and system automation control such as air conditioners, elevators, and building automation.

The main part of the car computer is the microcontroller, which is a circuit board that integrates a microprocessor (CPU), memory, and input and output interfaces. The microprocessor is the core component of the single-chip microcomputer. The microprocessor converts the input analog signal into a digital signal, and compares and processes the stored reference data to calculate the output value. The output signal is amplified by power to control the actuator.
