4 Channel WLED ESP32 Addressable Controller

GLEDOPTO GL-C-017WL-D 4-Output ESP32 WLED Addressable LED Controller

The GLEDOPTO GL-C-017WL-D is a Wi-Fi-enabled ESP32 WLED digital LED controller designed for addressable LED strip installations that need multiple independent outputs. It provides four output channels for separately connected digital LED strips and supports DC 5V, 12V and 24V input. The controller has a maximum total output current of 15A and is designed for flexible WLED lighting projects.

Key Features

• ESP32-based WLED digital LED controller
• Four independent addressable LED strip outputs
• Supports DC 5V, 12V and 24V input
• 15A maximum total output current
• Built-in digital microphone for sound-reactive lighting effects
• Wi-Fi connectivity for WLED control
• Quick-release terminal design for convenient wiring
• USB Type-C connection for firmware flashing
• Supports OTA firmware updates
• Compact flame-retardant PC enclosure

Four Independent Outputs

The GL-C-017WL-D provides four separate output channels for addressable LED strips. This makes it suitable for installations where multiple LED strips need to be connected and controlled independently through WLED.

Wide 5V, 12V and 24V Support

The controller accepts DC 5V, 12V or 24V input, allowing it to be used with addressable LED strip systems designed for those supply voltages. Always match the power supply voltage to the LED strip and follow the strip manufacturer's wiring requirements.

WLED and Wi-Fi Control

The GL-C-017WL-D uses an ESP32 platform and WLED for wireless control of compatible digital LED strips. WLED provides control through its web interface and supported apps, with configurable colours, effects, segments and other lighting settings.

Sound-Reactive Lighting

A built-in I2S PDM digital microphone enables sound-reactive lighting functions. Compatible WLED configurations can use audio input to synchronise lighting effects with music and ambient sound.

USB Type-C and OTA Updates

The controller supports firmware updates through its USB Type-C connection as well as over-the-air (OTA) updates. This provides convenient access for firmware maintenance and WLED configuration work.

Wiring and Installation

The controller uses quick-release terminals to simplify connections. Its documented four-output wiring provides power, ground and data connections for the connected digital LED strips. Use an appropriately rated DC power supply and wiring for the voltage and total current required by the connected LEDs.

Technical Specifications

Compatible Addressable LED Strips

The GL-C-017WL-D is intended for digital/addressable LED strips that are compatible with its WLED configuration and voltage range. Common compatible protocols documented for this model include WS2811, WS2812, SK6812, TM1814, WS2813 and WS2815. Confirm the exact LED protocol, data wiring and operating voltage of your strip before connecting it.

Important Power Note

The stated 15A rating is the maximum total output current for the controller. It is not a statement that every connected LED strip can draw 15A independently. The required power supply, wire gauge and LED-strip loading must be selected according to the actual LED installation and its current requirements.

Applications

• Addressable RGB and digital LED strip installations
• WLED home lighting projects
• Multi-zone decorative lighting
• Music and sound-reactive lighting installations
• DIY LED projects and custom lighting effects
• Projects requiring four independently wired LED outputs

Frequently Asked Questions
