ESP32-S3 PLC Architecture Discussion
Worked for 9 mins 54 sec
Completed the schematic fixes: RS485 now has TVS protection, optional 120Ω termination, and optional fail-safe biasing; the HR911105A MDI mapping was verified and corrected; L1/L2 were updated with production MPNs and larger footprints. ERC remains clean, and the details are saved in Schematic Review Before Layout.
Open items:
- Before layout, verify the physical pad numbering/orientation for HR911105A and D29.
- L2 meets current margin, but its library metadata does not confirm shielded construction; verify EMI or substitute a confirmed shielded equivalent.
Suggested next steps:
- Verify the two remaining footprint-orientation items.
- Decide whether to route TPS4H160 FAULT/THER diagnostics to the ESP32.
- Proceed to schematic-approved PCB placement once you accept the remaining notes.

I’ll read the attached text and apply it to the current schematic-review/remediation workflow before making any further changes.

Completed the final schematic-gate pass and updated Schematic Review Before Layout. D29 is verified, L2 is now a confirmed shielded Sumida inductor, and U8/U9 FAULT is routed to ESP32 GPIO15 with a 10kΩ pull-up; ERC remains clean.
Open items:
- Layout is still not approved: HR911105A symbol-footprint mapping remains Must Fix because the Flux symbol/footprint readout is ambiguous versus the datasheet.
Suggested next steps:
- Replace HR911105A with a clearly numbered MagJack part/footprint, or manually verify its symbol-footprint mapping.
- After that, update the approval table to “Pass” and proceed to PCB placement.
HOW TO DOWNLOAD SCHEMATIC AS PDF OR AS A ALTIUM PROJECT?
Thought for 8 sec
In Flux, use the Export options from the project UI:
- Open your project.
- Click Export / download from the top toolbar or project menu.
- Choose:
- PDF for schematic/documentation output.
- Altium if available in your export list; otherwise export standard manufacturing/interchange formats such as Gerber, ODB++, IPC-2581, BOM, and Pick-and-Place.
If you don’t see an Altium export option, Flux may not support direct Altium project export for this project. For help from Flux support, use: https://docs.flux.ai/Introduction/getting-support.
