Overview
Reflow 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 of 16 × 32 mm with 65 parts on 60 nets, routed with 424 tracks and 64 vias.
It is built around the WS2811F, ME6211C33U4AG-N and SDV301N3, with the XL-B1010RGBT-HF among its other parts. Its parts include 23 resistors, 18 diodes, 9 transistors, 5 ICs and 3 capacitors.

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 Reflow PCB?
It measures 16 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Reflow use?
65 parts, built around the WS2811F, ME6211C33U4AG-N, SDV301N3 and XL-B1010RGBT-HF. 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 Reflow KiCad files?
From the smkent/pcb repository on GitHub, at the commit this page was made from: the board is pcb-archived/jigs/reflow/reflow.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Reflow 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).
