Typical Applications
With two digital outputs, IP67 protection and a wide DC input voltage range, the controller can be used for a broad range of addressable LED installations.
Addressable LED Strips Control compatible digital LED strips and configure the corresponding LED IC type directly in WLED.
Outdoor LED Projects IP67 protection makes the controller suitable for appropriately designed outdoor lighting installations.
Architectural Lighting Create dynamic LED lines, decorative contours and multi-section lighting installations.
Music & Entertainment Use the integrated digital microphone for AudioReactive lighting effects.
DIY Pixel Lighting Ideal for individually configured WLED projects using compatible digital LED protocols.
Dual LED Zones Operate two digital LED outputs using GPIO16 and GPIO2 as the respective data connections.
WLED control via WiFi, app, browser and ESP-NOW
The controller is configured through WLED. On iOS, the WLED app can be used, while Android supports WLED or WLED Native. The WLED interface can also be accessed directly through a web browser.
For initial setup, the controller creates the WiFi network "WLED-AP". After connecting, the WiFi settings can be configured and the controller added to the local wireless network.
ESP-NOW support allows compatible WLED remote controls to be paired with the controller. The documented compatible remote models are GL-RC-001WL and GL-RC-002WL.
The digital microphone is configured for AudioReactive operation using Generic PDM with I2S SD on GPIO32 and I2S WS on GPIO15.

Note: The power supply voltage must match the connected LED strip. The total current, current per output and power requirements of the LED installation must be taken into account when selecting the power supply and planning additional power injection.
Installation Notes
- Disconnect the power supply completely before wiring or changing any connections.
- Use only a DC supply voltage that matches the connected LED strip.
- Connect the controller input correctly to V+ and V-.
- Connect each digital LED strip to V+, DATA and GND of the corresponding output.
- Output 1 uses GPIO16 and output 2 uses GPIO2 for the data signal.
- Do not exceed 15A total output current or 10A per channel.
- Configure the correct LED IC type and LED count in the WLED LED Preferences.
- Additional power injection may be required for long or high-current LED installations.
- Do not disassemble or wire the controller while it is powered.
- Power supplies, connectors and other components must also have suitable environmental protection for the installation location.
