README
README.mdPCB designs
A monorepository of my PCB designs created with KiCAD 8.
Layout and Workflow
Custom symbols and footprints are located in libraries, which
is shared between PCB projects using ${KIPRJMOD}.
Individual PCB projects (e.g. *.kicad_pro and friends) are located within
within pcb for active projects, or
pcb-archived for archived projects.
When a PCB is ordered from a project, fabrication outputs are created and
in the project's fab subdirectory and committed to the repository.
Setup
Ensure pipx is installed:
pip install pipxInstall scons:
pipx install sconsInstall KiCAD-related dependencies using the system site packages directory:
pipx install --system-site-packages kikit interactivehtmlbomBuild
To render all outputs, simply run scons.
To render outputs for a particular board, run scons -u within that board's
project subdirectory.

Questions
How big is the Esp lcd dev PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp lcd dev use?
39 parts, built around the VEML7700-TT, WS2812B-2020 and 2N7002DW. 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 Esp lcd dev KiCad files?
From the smkent/pcb repository on GitHub, at the commit this page was made from: the board is pcb-archived/stackable2/esp-lcd-dev/esp-lcd-dev.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp lcd dev design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
