- 5.5x2.1mm DC Socket: Common barrel jack for DC power adapters.
- Type-C Interface: Can be used for 5V power supply (requires a USB wall adapter, not PC USB).
5.2 LED Strip Wiring
The controller features quick-connect terminal blocks for easy and secure wiring. It supports up to four independent LED strips.
- Open the connector upwards.
- Insert the wires into the appropriate terminals (V+, GND, IO16, IO12, IO4, IO2, IO13, GND).
- Press down the connector to secure the wires.
Refer to the wiring diagrams below for connecting one, two, three, or four LED strips:
5.3 Network Connection
The controller can be connected to your network via wired Ethernet or wirelessly via WiFi.
- Wired Connection: Connect an Ethernet cable to the Ethernet port on the controller.
- Wireless Connection: The controller will broadcast a WLED-AP hotspot for initial setup. Once configured, it will connect to your specified WiFi network.
5.4 Initial WLED App Configuration
To configure the controller, download the WLED app. During initial setup, you will connect to the controller's WLED-AP hotspot to configure your home WiFi network and other settings.
6. Operation
