ESP32-S3 not outputting 5V to RGB LEDs but Arduino works fine
Hey guys, I’m having a weird issue with my ESP32-S3 DevKit and WS2812B/RGB LEDs.
I have a custom PCB powered through the ESP32-S3 USB-C. The LEDs are supposed to receive 5V from the board, but they barely light up and I only measure around ~0.40V on the LED power rails.
What confuses me is:
The PCB has no shorts between VCC and GND.
If I connect an Arduino 5V directly to the exact same LED power rails, everything works perfectly.
The LEDs themselves are NOT dead.
The ESP32 powers on normally and the TFT display works.
Data pin is connected (currently using GPIO8).
I already checked continuity and solder joints.
So it seems like the ESP32 board itself is not properly delivering 5V to the LED section.
Any ideas would help a lot because I’m losing my mind with this lol.
