READ BEFORE STARTING TO WORK

Github workflow:

ALWAYS work on your own branch

  1. Check that you're in the correct branch:

    • git branch --all
      • if your branch is highlated in green, you can go to step 2)
      • if your branch is highlated in red, follow the next steps:
        • git fetch --all
        • git checkout [name of your branch]
  2. Once you're in the right branch, always start pulling the changes:

    • git pull
  3. Often save your progress:

    • git add .
    • git commit -m "[Message describing the changes made]"
  4. At the end of your session, ore once you're happy with your work, push your progress on the repo:

    • git push

Questions

How big is the Good Boy Limiter PCB?

It measures 105.4 × 86.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Good Boy Limiter use?

111 parts, built around the ESP32-S3-WROOM-1-N8, SY8120B, B3B-XH-A(LF)(SN) and LM5069MM-2/NOPB. 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 Good Boy Limiter KiCad files?

From the JohnanLuca02/BYTE_Electronics repository on GitHub, at the commit this page was made from: the board is Good_Boy_Limiter/Good_Boy_Limiter.kicad_pcb and its schematic Good_Boy_Limiter/3V3_selector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Good Boy Limiter design in my own project?

Its repository states no licence, so its author keeps all rights: ask JohnanLuca02 before reusing the design.
