[Training Camp] [Lichuang EDA Practice Activities] Tuya Smart 665766A

The RGBCW light strip control created by Tuya Smart is controlled by the WB3S module. The light strip can be used as an ambient light or as a table lamp. The APP interface is simple and elegant, and is easy to operate. The circuit is powered by a 12V power supply and uses an LM1085 LDO with an output capacity of 3A. However, this is overkill and can be replaced by AMS1117-3.3V. You can use 5V or 12V light strips to connect, RGBCW common anode, cathode for PWM control. PWM uses AO3400, N-channel MOS tube, with a driving capacity of up to 5A, which can be used for most light strips. All the way to the Key button, click to turn on/off the light, double-click to open the "music mode", long press for 5S to switch modes, and can also be used to configure the network. The three 5P pin headers in the circuit diagram are convenient for switching the output of the two modules I bought. You don’t need to use them. You can slightly modify the circuit yourself.
