Notice: If you want to upgrade the firmware, please use "WLED_0.x.x_ESP32_audioreactive.bin"
 
The first rule of upgrading: If it ain't broke, don't fix it!
In other words, ensure that there is a good reason to mess with a working installation (e.g., a need to use a new feature or address a found problem fixed in the current version).
 
Custom version firmware
 
The device firmware uses DATA1 (GPIO18) as the DATA of the WS281X type light strip by default. If you have other types of light strips, please set it on the setting page according to your actual situation
