Learnings
Power management is key, especially with high-power components like addressable LEDs. Choose power sources with intention based on your build's needs, and minimize complexity if possible while achieving the required goal. Make sure to follow the datasheet for accurate board layouts and double-check USB connections and ESP32 pinouts!
