PCB Design Workflow
1:10
Organizing manufacturing details.
I’ll finish this project to a manufacturable, routed board. Here’s the plan I’ll run:
- Complete schematic: resolve dangling nets (including Net 35), verify power rails/portals, add required supporting passives per datasheets.
- Run ERC and fix issues; validate BOM entries and footprints.
- Prepare PCB: confirm rules/stackup, then use Auto‑Layout to place and route.
- Run DRC and resolve violations; iterate until clean.
- Finalize availability and export Gerbers, BOM, and pick‑and‑place.

Plan
- Complete the ESP32 smart scale project by finishing the schematic, resolving ERC/DRC issues, auto‑layout and route the PCB, and preparing manufacturing outputs to achieve a fully manufacturable design.
#Implementation plan
-
Schematic Completion and Review
- Complete all schematic connections including resolving dangling nets (e.g., Net 35).
- Verify power rails (PP12V0, PP5V0, PP3V3, PP3V3_L) and net portals are correctly connected.
- Add any required supporting passives as per datasheet recommendations for parts such as the ESP32‑C3, NAU7802 ADC, NCP176B 3.3 V LDO, and TPS62130 buck regulator.
-
ERC Validation and Correction
- Run ERC and identify issues such as missing pull‑ups, decoupling capacitors, or voltage ratings mismatches.
- Correct ERC warnings by connecting pull‑ups to the I2C bus (I2C_SCL, I2C_SDA) or other required connections and confirming BOM entries and footprints.
-
PCB Preparation and Auto‑Layout
- Finalize the PCB stackup and core design rules.
- Utilize Auto‑Layout to effectively place all components including the ESP32‑C3 module (IC1), NAU7802 ADC (U1), NCP176B (U2), TPS62130 (U3), USB‑C connector (J2), microSD (J1), and pin headers (J4/J5), ensuring signal integrity on I2C, SPI, and GPIO nets.
- Auto‑route nets and verify all connections, ensuring there are no missed connections or routing conflicts.
-
DRC Run and Optimization
- Run DRC and resolve clearance or rule violations.
- Adjust PCB layout rules as needed to clear design rule issues and route problem areas.
-
Finalization and Manufacturing Outputs
- Review component availability and update project properties if necessary.
- Export manufacturing files including Gerber files, BOM, and pick‑and‑place outputs.
#Success criteria
- All schematic connections are complete with no dangling nets or unconnected pins.
- ERC and DRC run without errors or warnings, addressing pull‑ups and decoupling as required.
- Auto‑Layout has successfully placed and routed all components with complete net connectivity.
- Final project outputs (Gerbers, BOM, pick‑and‑place files) are generated and ready for production.
