1 Distribution Board
About the 1 Distribution Board
1 Distribution Board is an open source PCB design by basicallysource, published on GitHub. It is a 2-layer board measuring 130 × 120 mm, with 179 components from 67 distinct parts.
Other key parts include the C5199039, C5378027, C5378003, R-78B12-2.0 and R-78B6.5-1.5. By type, the board carries 84 resistors, 56 connectors, 16 capacitors, 7 ICs, 7 diodes and 5 transistors.
From the project
Edit the YAML, push, open a PR. That's the whole workflow: no toolchain, no credentials, no publish step to remember. The PR's docs preview shows the PR's own drawings about 90 seconds after each push.

To look at a drawing before pushing, render it yourself:
Everything lands in wireharness/out/`, which is gitignored: a local render can never end up committed, even by accident. CI's render is still the canonical one (its graphviz is pinned; yours probably differs by a pixel or two, and the next CI run quietly normalizes the published copy).

1 Distribution Board: common questions
How big is the 1 Distribution Board?
The 1 Distribution Board measures 130 × 120 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 1 Distribution Board?
179 components, from 67 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 1 Distribution Board design files?
From the basicallysource/sorter-v2 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 1 Distribution Board design in my own project?
The repository has no license, so all rights stay with basicallysource. Use it as a reference, and ask the author before reusing the design.
