See exactly what Resin reports.

Six downloadable runs show literal error, warning, informational, and total counts. They are useful for understanding Resin's checker output, not for certifying a different design.

Check runs: 6
Zero-finding runs: 2 / 6
Reported findings: 241

Published runs

Four board checks and two schematic checks.

A zero count means the selected checker reported no findings for that exact file. It does not mean every possible rule or downstream requirement was exercised.

In the product

Results stay visible by severity and category.

This recorded pre-routing USB-to-CAN FD board shows 54 findings across eight categories. It demonstrates the result interface; it is not presented as a passing or manufacturing-ready board.

Native Resin DRC showing 54 findings for the USB-to-CAN FD pre-layout project — 5 errors / 31 warnings / 18 informational findings

Render of the CAN bus shield fixture used in a published DRC run — Downloadable fixture / 0 errors / 4 warnings

Filter by run, severity, diagnostic code, or rule category. Related rows can share one root cause, so totals are a starting point for review rather than a design score.

Use with your project

Run the same review on a representative board.

Confirm the rule set, resolve required findings, rerun after changes, and inspect manufacturing outputs independently. A passing fixture does not prove a different board is ready to build.
