Getting started
In depth version of how to get started 🏎️
Tools that we are using
- First, download KiCAD for your specific OS
- Next, make sure you have Git installed.
- GitHub Desktop If you are not tech savvy
- Git If you are tech savvy 😎
If you installed GitHub desktop, create an account and close the repository. I recommend cloning the repository into your documents folder.
How to clone repositories on GitHub desktop
The repository url is: https://github.com/formulaslug/fs-2-schematics
If you are tech savvy and using Git
$ git clone https://github.com/formulaslug/fs-2-schematics
- Setting the project file path correctly on KiCAD
Make sure KiCAD is currently open
Then click on preferences -> Configure Paths..
Click on the plus on the bottom right to add a new path variable
On the left, you want it FS_2_SCHEMATICS <- all caps
On the right, you want to set the path where you installed the repository (the folder is called fs-2-schematics)
Click on the folder on the right, and find fs-2-schematics repo like stated above
Should look something like this after its done
Example (might look different if you are using an Mac, or Linux):
| Left side | Right side |
|---|---|
| FS_2_SCHEMATICS | Docs\fs-2-schematics |
- Lastly, open up the project

Questions
How big is the BSPD PCB?
It measures 160 × 124.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BSPD use?
139 parts, built around the ISO1050DUB, MCP6004-E/P, HEF4093BT and LM555N. 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 BSPD KiCad files?
From the formulaslug/fs-2-schematics repository on GitHub, at the commit this page was made from: the board is BSPD/BSPD.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BSPD design in my own project?
Its repository states no licence, so its author keeps all rights: ask formulaslug before reusing the design.
