2. What should you know before using Sporniket's protoboard ?
Sporniket's protoboard is designed using Kicad, version 7.
Do not use Sporniket's protoboard if this project is not suitable for your project.
3. How to use Sporniket's protoboard ?
From sources
To get the latest available models, one must clone the git repository.
git clone https://github.com/sporniket/protoboard.gitThen, open the project in Kicad.
From github releases
A github schematic only release (with schematics in the release tag and name) will provide a PDF of the schematics
A github regular release will provide :
- A standalone Kicad project
- A PDF of the schematics
- A PDF of the silkscreen
- If applicable, a Gerber for boardmanufacturer. Some details may have been adapted for a specific manufacturer.
- If applicable, a BOM, and pick an place files, likely for a specific manufacturer too.

Questions
How big is the Project board grid smt PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Project board grid smt use?
1,755 parts. 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 Project board grid smt KiCad files?
From the feastorg/protokit repository on GitHub, at the commit this page was made from: the board is boards/project-board-grid-smt/project-board-grid-smt.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project board grid smt design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
