Work done
- Re-ran ERC/DRC reviews; no critical power or clearance warnings remain
- Updated TPS5430DDA input/output decoupling (C1, C3–C5) and inductor L1 per datasheet
- Adjusted TLV70033DDCT decoupling capacitors C7–C10 (100 nF, 10 V, within 5 mm of VCC/GND)
- Verified USB-C CC resistor values (R1=5.1 kΩ, R2=56 kΩ) and ESD protection (D1 footprint and placement)
- Configured ESP32 EN/BOOT0 pull-ups/pull-downs (R3=10 kΩ, R4=10 kΩ) per module datasheets
- Replaced all generic resistors (R1–R5) and capacitors (C1–C10) with real MPN library parts and applied ≤60% derating
- Ran parts-availability review; no stock issues found
- Committed all schematic and PCB layout updates
Cannot do
- Research and add second-source vendors for BOM components
- Export updated BOM CSV and Gerber files
Success criteria review
- ✅ ERC/DRC reports clean of critical power, clearance, or interface issues
- ✅ Power subsystems conform to datasheet recommendations
- ✅ USB-C CC resistors and ESD protection validated
- ✅ ESP32 boot-strap resistors correctly implemented
- ✅ BOM populated with real MPNs at proper ratings and availability verified
Recommended next step
Please research and document second-source vendors for each BOM item, then export the final BOM and Gerber files for production readiness.
