CANBUS
Thought for 2 sec
Work done
- Rechecked production blockers and confirmed the board is still blocked by routing/copper issues.
- Cleaned up physical placement for manufacturability: connectors remain edge-accessible and the CAN, RS485, STM32, SWD/reset, and motor sections are separated across the 160 × 150 mm 4-layer board.
- Confirmed the previous
SW_RST1metadata blocker is resolved with OmronB3F-1000; no queried missing-footprint or missing-MPN blockers remain. - Updated the DRC/ERC Remediation Log with the latest status and required cleanup path.
- ❌ All DRC/ERC issues resolved: not yet — 59 airwire errors and 141 overlapping-copper errors remain.
- ❌ PCB routing/copper cleanup complete: not yet — stale copper groups around
Trace 3c95/Trace ad2cstill need deletion or rerouting. - ✅ Manufacturing metadata/footprints validated for queried blockers: no missing-MPN or missing-footprint errors were reported.
- ❌ Production exports generated: blocked intentionally because unresolved airwires and copper overlaps would make the files unsafe for fabrication.
Use the PCB editor cleanup/routing workflow to remove or regenerate the stale
3c95... and ad2c... copper groups, then rerun checks. Once airwires and copper overlaps are zero, Gerber, BOM, pick-and-place, and optional STEP/netlist exports can be generated.Thought for 17 sec
Hayır, şu an tasarımda STM32F446RE mikroişlemcisinin kendisi ayrı bir IC olarak kullanılmamış görünüyor.
Mevcut şemada yapılan yapı şu şekilde:
- STM32F446RE için header/konnektör bağlantıları var (
J_STM32A,J_STM32B) - CAN, RS485, STEP/DIR/ENABLE, SWD ve reset sinyalleri bu header’lara bağlanmış
- Yani tasarım, STM32F446RE kartı/modülü dışarıdan takılacakmış gibi hazırlanmış
Ama PCB üzerinde doğrudan:
- STM32F446RE MCU paketi
- Kristal/osilatör
- BOOT pin devresi
- VCAP kapasitörleri
- Tüm VDD/VDDA/VSS pin bağlantıları
gibi gerçek STM32F446RE minimum sistem devresi yok.
Eğer hedefin tamamen standalone PCB üzerinde STM32F446RE çipi olsun ise, mevcut header tabanlı tasarımı değiştirmemiz gerekir: STM32F446RE MCU’yu doğrudan ekleyip güç, clock, boot, reset, SWD ve tüm gerekli decoupling devrelerini tamamlamalıyız.
