Overview
Lcd round is an open-source printed circuit board by smkent, from the smkent/pcb repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board with 16 parts on 10 nets, routed with 121 tracks and 32 vias.
It is built around the BSS138. Its parts include 3 resistors, 3 connectors, 2 capacitors and 1 transistor. It belongs with the lEDs and displays boards of this library.

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
What parts does the Lcd round use?
16 parts, built around the BSS138. 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 Lcd round KiCad files?
From the smkent/pcb repository on GitHub, at the commit this page was made from: the board is pcb-archived/stackable2/lcd-round/lcd-round.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lcd round 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).
