GLEDOPTO GL-C-616WL – WLED Controller with ESP32, UART and Ethernet

The GLEDOPTO GL-C-616WL is a powerful WLED controller based on the ESP32, offering both WiFi and Ethernet connectivity for flexible and stable smart lighting integration. It supports control of up to two digital LED strips in parallel, making it suitable for advanced lighting projects and creative installations.

The controller features a UART Type-C interface for flashing and configuration and is compatible with popular pixel LED chipsets including WS2812B, WS2815, SK6812, UCS2903B and SM16703. Control is handled via the WLED App on iOS and Android, with support for music-synchronised effects through the integrated AudioReactive microphone.

It operates on a wide DC input voltage range of 5 to 24 V, delivers up to 15 A total output, and supports up to 10 A per channel. For safety and efficiency, it includes an integrated relay and fuse. Network setup can be completed via WiFi or a wired Ethernet connection, with full configuration available through the WLED web interface.

The GL-C-616WL is ideal for digital LED strip lighting, Ambilight-style setups, smart home integrations, and ESP32-based DIY projects where reliability and performance are essential.
