I’ll resolve the manufacturing metadata by reviewing the missing-MPN/package checks, selecting reasonable real parts/packages for passives/connectors where possible, updating properties, then re-running the checks.
I found real MPNs for the missing passives and headers, and a documented Pololu N20 encoder motor option. I’m applying those now; the exact motor ratio remains a selectable BOM decision.
Updated the missing manufacturing metadata and re-ran the relevant checks.
What I fixed:
Added MPN/manufacturer/package metadata for:
HC-SR04 divider resistors
I2C pull-up resistors
3.3V and 5V bulk capacitors
Raspberry Pi 40-pin socket/header interface
Servo header
Four encoder headers
Four N20 motor placeholders
Used real sourced parts where available, including Yageo resistors, Samsung/Panasonic capacitors, Harwin headers, and Sullins Raspberry Pi header.
Added a provisional Pololu N20 encoder motor choice for the motor BOM entries.
Verification result:
The manufacturing checks for missing MPNs and missing footprints returned no open errors or warnings.
Remaining note:
ACUs are now unavailable, so I can’t continue further right now. The next recommended step is to review the provisional motor choice/gear ratio before layout or manufacturing, since N20 encoder motor MPNs depend heavily on RPM and gear ratio.
