Overview
Example project is an open-source printed circuit board by wang-edward, from the wang-edward/autoplace repository on GitHub. It is a 2-layer board of 77.1 × 33.4 mm with 11 parts on 42 nets.
It is built around the TPS7A4101DGN and NRJ3HF-1. Its parts include 6 capacitors, 2 resistors, 2 ICs and 1 connector. It belongs with the STM32 boards of this library.

README
README.mdAutoplace
This is a kicad plugin to help in the intial layout of a board. It "solves" a component placement by minimizing wirelength while smoothing out density.
This isn't meant to one-shot a component layout, but as a helpful first step to group related components.
It works best when Edge.Cuts is well defined, and static components (like ports) are locked.
Installation
Symlink autoplace/ into the plugins folder:
MacOS
ln -s "$(pwd)/autoplace" ~/Documents/KiCad/10.0/plugins/autoplace # KiCad 10Linux
ln -s "$(pwd)/autoplace" ~/.local/share/KiCad/10.0/plugins/autoplace # KiCad 10The idea is based on the DreamPlace algorithm: https://github.com/limbo018/DREAMPlace

Questions
How big is the Example project PCB?
It measures 77.1 × 33.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Example project use?
11 parts, built around the TPS7A4101DGN and NRJ3HF-1. 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 Example project KiCad files?
From the wang-edward/autoplace repository on GitHub, at the commit this page was made from: the board is example_project/example_project.kicad_pcb and its schematic example_project/example_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Example project design in my own project?
Its repository states no licence, so its author keeps all rights: ask wang-edward before reusing the design.
