I don’t have those 12v RGBW w/UCS2904 Leds yet, so I can’t try.
Received a more information from the seller:
1./ was told that both UCS2904 and TM1814 are using the same signal.
— under the Wled’s Compatible LED Strips list, Wled supports the TM1814 (12v, RGBW) —
2./ UCS2904 ic will work with any SPI protocol controller. (Not sure any difference between ESP32 vs SPI?)
It might work based on those information from seller, hopefully someone test it before can give some input here.
