Toolbox: common questions
How big is the Toolbox PCB?
The Toolbox measures 80.9 × 128.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Toolbox?
272 components, from 83 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Toolbox design files?
From the StudioKAT/Toolbox repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Toolbox design in my own project?
The repository has no license, so all rights stay with StudioKAT. Use it as a reference, and ask the author before reusing the design.
