Versions
(Not all tags shown)
- [REV0.0.2]
- changed GPIO3 with GPIO12 between R3 and R8 because GPIO12 cannot be pulled high while in flash mode
- added 100nF in parallel with R7 for better battery voltage level reading
- modified the i2c connector label for better visibility
- adjusted the position of the solder-jumper labels
- increased the copper fill area under the uC for better cooling

Questions
How big is the REV0.0.2 UIECRE GS CARBON S2 PCB?
It measures 37 × 18 mm and has 4 copper layers, 1.6 mm thick.
What parts does the REV0.0.2 UIECRE GS CARBON S2 use?
74 parts, built around the TS342A2P-WZ. 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 REV0.0.2 UIECRE GS CARBON S2 KiCad files?
From the GroundStudio/GroundStudio_Carbon_S2 repository on GitHub, at the commit this page was made from: the board is Hardware/REV0.0.2 - Kicad6/REV0.0.2 UIECRE_GS CARBON S2.kicad_pcb and its schematic Hardware/REV0.0.2 - Kicad6/REV0.0.2 UIECRE_GS CARBON S2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the REV0.0.2 UIECRE GS CARBON S2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask GroundStudio before reusing the design.
