5.2. Wiring Instructions
The controller features quick connect ports for easy wiring. Follow these steps:
- Open the connector upwards.
- Insert the wire (suggested 0.34-4mm² / 22-12AWG) into the appropriate terminal.
- Press down on the connector to secure the wire.
For connecting your LED strip:
- The group of 'D' for GPIO16 is the default data output. Use this group first for your LED strip's data line.
- The other group of 'D' is GPIO2, which can be used after configuration on the WLED APP.
- Connect V to VCC (positive power) and G to GND (ground).

6.2. Button Functions
The controller features two buttons: Reset and Opt.
- Reset Button: Pressing this button will put the controller module in a powered-off state, making the WLED controller unusable. Releasing the button will power the module back on. This button is useful for powering the controller on and off when it's inconvenient to access the power supply.
- Opt Button:
- Short press: Power on/off.
- Long press for 1 second: Switch colors.
- Long press for more than 10 seconds: The WLED device will be reset to factory settings, and the WLED-AP hotspot will be activated. Do not use unless it is an emergency or if the factory settings have been restored.
