petite boîte toute minuscule, mais absolument géniale, surtout avec l'application wled ! ça fonctionne direct en sortie de boîte. il faut utiliser le code Wi-Fi : wled1234 que j'ai un peu galéré à trouver. (source: https://www.aliexpress.com/item/1005005924589439.html)

For FCOB WS2811 12V lights, I want to use a 12V 10A power supply. Can i plug that into this controller?
The administration's response:
with such large currents, it is better to supply power directly to the LED strip. The power supply of the controller can be connected in parallel to the LED strip

I have a controller that will not fully boot until I download logs. after that, it works fine. My intent is to have this run from a wall wart and not tethered to a pc. any ideas of what is causing this? I have reloaded the firmware from your download site and got the same issue.
The administration's response:
Please contact support https://smlight.tech/support/
I am sure we will solve your problem

I have updated WLED and lost sound reactive capabilities.
I can try to reconfigure it manually but I need to know the microphone pin number.
What pin is microphone on?
The administration's response:
Pins are written right on the cover of the device.
WS -> GPIO15
SC -> GPIO14
SD -> GPIO32

Mine came loaded with SR version but can't seem to update to version 14 b3. Used your tool to update which made it unresponsive. Reverted back to the old version and it came whack alive. I need to update to latest version to gain access to new effects etc.
The administration's response:
Use this tool to update https://smlight.tech/flasher/#SLWF-03
The firmware in it is preconfigured
Have a look on this
