History and licenses

Most imported projects retain their original commits as merge ancestry. Some former standalone repositories have since been removed after verification. Projects with contaminated secret history may be imported as sanitized snapshots instead. Existing per-project license files and notices remain authoritative for their respective project directories; there is intentionally no repository-wide license override.

Questions

How big is the Out PCB?

It measures 27.9 × 55.9 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Out use?

43 parts, built around the AXP2101 and TPS22917LDBV. 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 Out KiCad files?

From the MichalMatu/hardware-lab repository on GitHub, at the commit this page was made from: the board is projects/pcb/archive/boards/esp32_s3_hat_experiment/out/project.kicad_pcb and its schematic projects/pcb/archive/legacy_tooling/templates/skidl_reference/tests/examples/netlist_to_skidl/kicad_project/esp32s3mini1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Out design in my own project?

Its repository states no licence, so its author keeps all rights: ask MichalMatu before reusing the design.
