pixalynx/cm5-minimal-carrier

A 4-layer Raspberry Pi CM5 carrier board routes USB‑C 5V power through an RT9742 load switch with TVS protection and capacitive filtering, while providing ESD-protected HDMI output, CM5 connectors, test points, and ground/power planes.

# Imported catalogue parts

U1 (`RT9742SNGV`, C3235509) and D1 (`SMAJ5.0A-13-F`, C87074) were found with `tsci search --jlcpcb --json` and imported with `tsci import --jlcpcb --download --use-exact-footprint` on 18 September 2026. The original downloaded OBJ and STEP assets are retained beside each component.

The generated wrappers expose their CAD definitions. U1 accepts the board’s existing numbered pin aliases. D1 uses a diode element instead of the importer’s generic chip, preserving electrical semantics and avoiding a spurious supply-pin warning. The main board overrides both imported footprints with its reviewed footprints and preserves its symbols and net assignments.

U1’s imported land pattern is rotated 180° from ours: importer pin 1 is lower-right, while our pin 1 is upper-left. The board adds 180° to its 90° CAD offset (270° total). D1 pin 1 is the cathode at the left in both footprints. These imports do not replace the reviewed pad sizes, traces, vias, or clearances.

Search evidence and asset hashes: [imported-parts-review.json](https://tscircuit.com/pixalynx/cm5-minimal-carrier/blob/docs/imported-parts-review.json). A catalogue model is a visual aid; it does not replace the manufacturer’s mechanical drawing or assembly review.
