Built Prototype Revision A — Not Production Validated in the schematic.
What was accomplished:
Created a provisional RTX1090R1 Flux component from the public datasheet.
Built wired transmitter and receiver schematic blocks: RF, codec, XLR audio, USB-C charging, Li-ion power path, fuel gauge, 3.3 V rails, and ±5 V analog rails.
Cleared floating-pin and single-pin-net ERC issues.
Documented remaining power/ERC caveats and RF production dependencies.
Remaining ERC findings are Missing Power warnings tied to provisional/generated rails and RTX module output pins; they are documented in the verification notes.
PCB layout is not started yet.
RF antenna layout is placeholder-only until RTX/RMED reference files are available.
Suggested next steps:
Review the schematic and verification notes.
Proceed to schematic cleanup/arrangement.
Define board outline and stackup for the 25 mm-wide Rev A PCB.
Start placement with RF/audio/power separation and antenna keepouts.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
