PCB Layout for Tasmota Controlled (ESP8266) Christmas Tree Miniature Village Display
Summary:
This project primarily contains the hardware considerations for a Tasmota-based ESP32-centric control system for a custom Christmas Tree design which has multiple "layers" or "tiers" which each support and hold parts of a miniature villiage.
Design Render:
The finalized PCB render is shown here:
License:
This project is ultimately a custom design, but should not be thought of as "private", it is licensed openly such that anyone interested may consume the existing design and modify as desired.

Questions
How big is the TasmoTree PCB?
It measures 99.6 × 99.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TasmoTree use?
26 parts, built around the ESP8266EX, PSMN027-100PS and EC2-12NU. 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 TasmoTree KiCad files?
From the engineerjoe440/TasmoTree repository on GitHub, at the commit this page was made from: the board is TasmoTree/TasmoTree.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TasmoTree design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
