WLED  Slim Addressable LED strip controller
 
Please note that this controller does not have a microphone
 
Powered through USB-C, the controller is designed specifically for 5V three-wire addressable LED strips. Its slim profile makes it suitable for installation behind displays, under cabinets, inside light bars and in other spaces where a standard controller may be too large.
A built-in 5V logic-level converter provides a stronger and more reliable data signal for compatible LED strips.

Important Compatibility Information
This controller supports only 5V three-wire addressable LED strips.
A compatible strip normally uses the following three connections:
5V positive
Data
Ground
Compatible LED types may include:
WS2812B
5V WS2811
SK6812
SK6812 RGBW
WS2813
Other WLED-compatible 5V three-wire addressable LEDs
Always check the voltage, wiring order and communication protocol of your LED strip before connecting it.
 
Built-in 5V Logic-Level Converter
Many addressable LED strips are designed to receive a data signal close to their 5V operating voltage.
The built-in logic-level converter raises the controller’s data signal to 5V logic, helping provide:
More reliable LED data transmission
Improved compatibility with 5V addressable strips
Reduced flickering caused by a weak data signal
Better signal stability in suitable installations
The logic-level converter improves the data signal only. It does not increase the available power output.
 
Home Assistant Integration
The controller can be added to Home Assistant through the WLED integration.
Depending on your WLED configuration, you can:
Turn the LED strip on or off
Adjust brightness and color
Select WLED effects and presets
Include the strip in scenes
Create time-based automations
Synchronize lighting with sensors
Trigger effects from buttons or events
Control lighting from a Home Assistant dashboard
 
USB-C Power
The controller operates from a regulated 5V USB-C power source.
Suitable power sources may include:
USB-C wall adapters
USB power banks
Computer USB ports
Powered USB hubs
The power supply and USB cable must provide sufficient current for the controller and the connected LEDs.
The USB-C connector is intended for 5V power input. Do not assume that it supports USB data or firmware flashing unless explicitly stated for the selected product version.

Basic Installation
Confirm that the LED strip is a compatible 5V three-wire addressable model.
Check the 5V, Data and Ground wiring order.
Connect the LED strip with power disconnected.
Connect a regulated 5V USB-C power supply.
Configure the controller on a 2.4 GHz Wi-Fi network.
Open the WLED interface.
Select the correct LED type, color order and LED count.
Begin testing at a low brightness level.
 
Power and Wiring Notes
Use a regulated 5V power supply only.
The power supply capacity must be sufficient for the total number of LEDs.
Full-white output normally uses significantly more power than colored effects.
USB ports, cables and adapters have different current limits.
Long strips may require separate 5V power injection.
Connect all power-injection grounds together.
Do not route high LED current through thin wires.
Keep the data wire reasonably short where possible.
Reduce the WLED brightness limit if the USB power source has limited capacity.
Maximum LED quantity depends on the power supply, USB cable, wiring, effects and WLED configuration.

Important Notes
This controller supports only 5V three-wire addressable LED strips.
Do not connect a 12V or 24V power supply.
Check the strip pin order before connecting power.
Incorrect voltage or reversed wiring may permanently damage the controller or LED strip.
A built-in logic-level converter improves the data signal but does not increase power capacity.
Large LED installations require an appropriately sized external power supply and may require power injection.
Wi-Fi control normally requires a 2.4 GHz network.
This product is intended for indoor DIY and decorative lighting applications.
