🔌 IO Pin Assignment (Our Controller Platform)

The controller is based on an ESP32 platform with the following GPIO assignments.

💡 1. LED Data Outputs

Function GPIO Pin Description
Data_GPIO_OUT1 GPIO2 Primary LED data output 1
Data_GPIO_OUT2 GPIO15 Secondary LED data output 2

Used as pixel LED data lines (WS281x, SM16703, SM16825, RGBW/RGBWY).

🎛 2. Buttons

Function GPIO Pin Description
Button 0 GPIO0 User button 0
Button 1 GPIO25 User button 1

These can be mapped in WLED for power toggle, preset cycling, playlist control, etc.
