Trying to replace a ESP-32/breadboard with WLED (working) with these simple LS3P-WLED controllers. Installation went perfect, AP connect to WiFi, restore config etc. Go to connect LEDs, nothing. Will not turn on. bought 4 LS3P-WLED and so far 2 of them won't work. Plug back in ESP32 and it works.
Tried: different PS, cable
LEDs are BTF-lighting WS2812B
