Cerberus Proto Board

Cerberus expansion starter

An editable starting point for Cerberus expansion boards: four 20-pin header footprints, their connector schematic, and a prototyping area. This is the expansion board project.

Open the project

Use KiCad 10.0 or a compatible newer version. Extract the complete starter ZIP, then open Cerberus_Proto_Board.kicad_pro. Keep the project, PCB, and schematic together with their matching filenames.

Libraries and models

The connectors use standard 2.54 mm, 1 × 20 pin-header footprints. Symbols are embedded in the schematic. The custom protoboard footprint geometry is embedded in the PCB; a separate custom footprint library was not supplied. Save that embedded footprint into your own library before using library-based footprint updates.

Header 3D models reference KiCad 10's standard ${KICAD10_3DMODEL_DIR} library. Install the standard 3D-model library for those previews. The custom prototyping footprint retains a generic header model, so the 3D view is not a verified mechanical model.

Using the starter

Check connector references and pin-1 markers against the Cerberus pinout when positioning an add-on. Preserve the shared-bus and startup-pin requirements in that reference. Verify net assignments, board clearance, and your changes before fabrication.
