Overview
Crobug is an open-source printed circuit board by neggles, from the neggles/crobug repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 24 × 12.5 mm with 10 parts on 19 nets, routed with 91 tracks and 18 vias.
It is built around the SL2.1S. Its parts include 4 capacitors, 2 resistors, 2 connectors, 1 IC and 1 crystal.

Building
building most likely does not work at the moment.
(I need to update kikit stuff to deal with KiCad 6 and also actually specify board dimensions, panel tabs etc still.)
Simply call make in the top-top level directory. The build directory will then contain:
- the main board and top board
- A panelized version of said boards
- zipped gerbers for the boards you can directly use for manufacturing
Credit where it's due:
Makefile uses Jan Mrázek's KiKit,
which I cannot recommend enough and will need to be available before running make
Jan's jlcparts app was also extremely useful in narrowing down part choices based on what JLCPCB have available.

Questions
How big is the Crobug PCB?
It measures 24 × 12.5 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Crobug use?
10 parts, built around the SL2.1S. 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 Crobug KiCad files?
From the neggles/crobug repository on GitHub, at the commit this page was made from: the board is crobug/crobug.kicad_pcb and its schematic crobug-direct/crobug-direct.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Crobug 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).
