RayRigAntSw is RF StateSide LLC's through-hole RF relay board for selecting two rigs, three antennas and an amplifier/bypass path.
Public Engineering Reference — AS-IS. The editable design, BOM and manufacturing files support study, independent construction, modification and community improvement.
Five 12 V SPDT relays provide RF routing through external low-side drivers. Two PTT connections pass to the external controller. RaySspaController supplied the drivers and sequencing used in our original integration test; another controller can use the documented interface.
The original PCBWay boards were assembled and successfully tested. D1–D5 were installed opposite the original PCB markings to obtain correct electrical polarity. The supplied CAD includes the subsequent correction and was not refabricated. See assembly and history.
Open the KiCad 9 project. Required symbols and footprints are included in project-local libraries. Optional 3D models are not required or bundled.
The integration guide provides the eight-pin J8 interface, relay truth tables and external-driver requirements. The board does not enforce transmitter arbitration or switching delays; those responsibilities belong to the external controller.

Use the BOM with the P2-prep-01 manufacturing set. This identifier ties the corrected sources to their outputs; it does not identify a newly tested board. The original v2.0 silkscreen is retained.
Four inherited clearance findings, two J6 courtyard findings and nine schematic ERC findings are documented in the engineering audit. The supplied files are not represented as DRC/ERC-clean. Assess the retained findings and component/mechanical suitability before manufacture.

Original fabrication archives and internal review records are retained separately. No parent firmware or development-repository history is included.
KiCad was used for schematic capture and PCB design. Python utilities support source verification and manufacturing-package integrity checks. Git and GitHub are the intended version-control and distribution tools.
ChatGPT by OpenAI and OpenAI Codex assisted with engineering review, documentation, source organization, validation and preparation of the open-hardware reference. RF StateSide LLC performed the original hardware design, assembly and historical integration testing.
No guaranteed RF power handling, isolation, insertion loss, frequency range, hot-switching capability or certification is claimed. The corrected CAD has not been physically refabricated. No future development or technical support is promised. Read known limitations.
