I have an ESP-WROOM-32 with a CP2102 chip, and I’m trying to connect it directly to a WS2812B (5V), but the LEDs won’t light up. I’ve checked everything with a multimeter, and there don’t seem to be any issues. The ground, 5V, and control pin are all properly connected to GPIO2.
I’ve attached some pictures of my setup for reference. Any ideas?
Thank you so much for your prompt response!
I followed your advice, flipped the LED strip, soldered everything, and connected it to the external power source (instead of through the Type-C). Now it works perfectly!
