README
README.mdLook At My Shiny Crystal Balls!
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.

Questions
How big is the Esp32-crystal ball PCB?
It measures 48.7 × 44.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-crystal ball use?
54 parts, built around the ESP32-S3-MINI-1-N8, SN74LV1T34DBV, OWMMOD-403010A-S261F and TP4057. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Esp32-crystal ball KiCad files?
From the atomic14/esp32-crystal-balls repository on GitHub, at the commit this page was made from: the board is esp32-crystal-ball.kicad_pcb and its schematic esp32-crystal-ball.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-crystal ball design in my own project?
Its repository states no licence, so its author keeps all rights: ask atomic14 before reusing the design.
