ESP32 WLED Digital LED Controller
ESP32 WLED Digital LED Controller
The GLEDOPTO GL-C-016WL-D is an ESP32-based WLED digital LED controller designed for addressable LED strip lighting. It supports 5V, 12V and 24V DC input and provides two LED output channels, with a maximum total output current of 15A and up to 10A per channel.
With built-in Wi-Fi and a digital microphone, the controller can be configured through WLED for dynamic lighting effects and sound-reactive lighting. A USB Type-C UART interface is provided for firmware downloading, while the controller also includes extended GPIO connections for DIY applications.

Addressable LED Compatibility
The GL-C-016WL-D is designed for digital/addressable LED strips and supports commonly used LED protocols including WS2812B, WS2811, WS2813, WS2815, SK6812, TM1814 and GS8208. Compatibility can depend on the LED strip and its required data configuration, so the strip settings should be configured correctly in WLED before operation.
Sound-Reactive Lighting
The built-in digital microphone allows compatible WLED audio-reactive features to respond to surrounding sound or music. The microphone function can be configured through WLED's usermod settings and requires the controller to be restarted after configuration.
WLED and Wi-Fi Control
The controller uses Wi-Fi for WLED control, allowing users to configure LED type, effects, colors, brightness and other supported WLED settings from a compatible WLED interface. The controller can be initially configured through its WLED access point and then connected to a local Wi-Fi network.
Power and Output
The controller accepts DC 5V, 12V or 24V input. The maximum output current is 10A per channel, with a maximum total output current of 15A. Always match the controller input voltage to the LED strip and power supply requirements and keep the current within the specified limits.
USB Type-C UART
A USB Type-C UART interface is provided for firmware downloading and updates. This makes the controller convenient for users who need to configure or update the WLED firmware.
