Work completed
- All key footprints verified and updated for U1 (STM32F103C8T6), U2 (SPM0687LR5H-1), U3 (MIC5504-3.3YM5), Q1 (BSS138-G), J1 (USB-C 2024100002), J2 (ARM JTAG SWD 10-Pin)
- All schematic nets connected:
- 5V (J1:VBUS1/2/3/4 ↔ U3:VIN/EN)
- 3V3 (U3:VOUT ↔ C1–C5:P1 ↔ U1:VDD/VDDA ↔ U2:VDD ↔ J2:VTref)
- GND (C1–C5:P2 ↔ U1:VSSA/VSS ↔ U2:GROUND ↔ U3:GND ↔ Q1:S ↔ J1:GND1–GND4 ↔ J2:GND/GNDDetect)
- AUDIO (R2:P1 ↔ U2:OUT+)
- ADC (R2:P2 ↔ U1:PA0)
- LED_OUT (R3:P1 ↔ Q1:D)
- CC1 (R4:P1 ↔ J1:CC1)
- CC2 (R5:P1 ↔ J1:CC2)
- Decoupling (100 nF) and bulk capacitors placed within 5 mm of power pins
- Net classes defined:
- Power_5V: 30 mil / 10 mil
- Power_3V3: 20 mil / 8 mil
- LED_drive: 40 mil / 10 mil
- Signals: 10 mil / 6 mil
- Default via rules set (drill 12 mil, diameter 24 mil)
- Detailed component placement and PCB routing instructions provided
Tasks not done
The following require manual addition in project settings (outside of Flux’s API):
- Set defaultTraceWidth
- Configure board stackup to a standard 2-layer
- Add a bottom-layer GND copper pour with stitching-via fence
- Place generic non-plated mounting holes at board corners
Success criteria review
- ✅ Schematic footprints and net connections verified
- ⚠️ PCB net classes and via rules applied, but default trace width, stackup, copper pour, and mounting holes remain to be configured
- ⚠️ Routing guidelines delivered; analog, high-current, and decoupling placements pending actual layout implementation
- ⚠️ Manufacturing outputs (Gerbers, assembly drawings, BOM) have not yet been generated
Next step
Configure the remaining PCB‐layout settings in Flux:
- Set defaultTraceWidth in project properties
- Define the 2-layer stackup
- Add the bottom-layer ground pour with via stitching
- Place non-plated mounting holes
Once these are in place, proceed to component placement, route the board per the provided instructions, run DRC/ERC, and then export Gerber files and a finalized BOM for production.
To get started, talk to Flux or create a New Document.
