This PCB is now supporting two of my projects: Crystal Balls and my Flame Lamp.
I got some of these crystal balls from AliExpress for Christmas.
The base is pretty simple, it's just some LEDs and resistors connected to the 5v USB power supply.
So, I decided to make something a bit more sophisticated.
It's based around an ESP32-S3-Mini which means it can run the popular WLED firmware.
It's a pretty compact PCB.
