Work completed:
- System architecture defined and saved
- ESP32, USB-C panel connector, BNC connector, sensor connectors added
- 3.3 V regulator and decoupling capacitors placed
- Pull-ups (4.7 kΩ), RC filters, ESD diodes added and nets connected
- ERC-driven reviews done, passive/component footprints set, MPN replacements applied
Remaining tasks:
- Define cable-gland keep-out zones, hydrophobic vent placement, and mounting-hole locations in PCB layout
- Classify nets and assign trace widths, configure copper pours and power planes
- Place components and route nets on PCB
- Perform PCB DRC/ERC in layout and resolve any issues
- Develop firmware scaffold and bring-up checklist (outside Flux scope)
Success criteria status:
- Schematic is complete with pull-ups, RC filters, decoupling caps, ESD protection: ✅
- PCB mechanical allowances (holes, glands, vent) still need layout placement: ❌
- Layout separation of analog/RF signals pending routing: ❌
- Firmware scaffold and bring-up documentation pending: ❌
- ERC/DRC is clean in schematic; layout checks pending: ❌
Next step: Prepare the PCB layout mechanical provisioning step—define mounting holes, cable-gland keep-outs, and vent footprint per the IP65 enclosure in the “Prepare PCB Layout” phase of the workflow.
