Based on ESP32 chip: The WLED controller uses a high-performance ESP32 chip, ensuring strong processing power and stable network connectivity. Microphone function: The built-in microphone can capture environmental sounds, allowing the lights to synchronize with music rhythms or sound changes, creating dynamic lighting effects. Low Power Consumption: On-board switching regulator powering the ESP32. Efficient idle operation with a built-in MOSFET relay to disable output power when WLED is off. UART download port: It is convenient for users to upgrade the firmware or debug the device through the serial port, without complex hardware operations. Simple wiring and expandability: The controller is designed with simple wiring ports, making it easy for users to quickly connect. In addition, the added IO33 port provides more customization options, supporting DIY enthusiasts to expand functionality according to their own creativity. Rich dynamic modes and compatibility: Offering over 100 dynamic modes, users can easily create lighting effects. At the same time, the controller is compatible with a variety of addressable LED strips, such as ws2811, ws2812, ws2813, sk6812, etc., increasing its range of application.
