NeuroRover V1 Schematic Design

flux

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.
