　　Functional module division: Divide the functions of the hair dryer into different modules, such as power management, wind speed control, temperature control, safety protection, etc.

　　Main control chip selection: Choose a suitable main control chip with sufficient computing power and IO interface, which can integrate control of various functional modules.

　　Power management: Integrate appropriate power management modules, including power input protection, voltage stabilizing circuits, switching power supplies, etc., to ensure stable and reliable power supply.

　　Driver circuit: Design a circuit suitable for high-speed fan drive, usually using MOSFET and other components to achieve precise control of the fan.

　　Sensors: Integrated temperature sensors, overcurrent protection sensors, etc., used to monitor and protect fans and circuits.

　　User interface: Consider adding LED display, buttons, and other user interface elements to PCBA to achieve user operation and status display.

　　PCB layout and wiring: Carry out good PCB layout and wiring to ensure signal integrity and EMI (electromagnetic interference) control.

　　Thermal management: Consider the heat dissipation design of PCBA to avoid potential issues caused by overheating.
