Christmas Tree PCB/README.mdChristmas-Tree-PCB
Last Christmas I made 3D printed cookie cutters and this Christmas I wanted to make a cool electronics project. I designed a Christmas tree PCB in kicad and then ordered it online at jlcpcb.com. Few LEDs, 2 10 Ohm resistors, battery box and you have a great Christmas ornament or gift :)

Questions
How big is the EnocderDriver PCB?
It measures 84.3 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EnocderDriver use?
35 parts, built around the ATMEGA8-16AU, L293D, LM1117-3.3 and LM1117-5.0. 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 EnocderDriver KiCad files?
From the NikodemBartnik/Small-Projects repository on GitHub, at the commit this page was made from: the board is Encoded Motor Driver/EnocderDriver/EnocderDriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EnocderDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask NikodemBartnik before reusing the design.
