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_RST1 metadata blocker is resolved with Omron B3F-1000; no queried missing-footprint or missing-MPN blockers remain.
Updated the DRC/ERC Remediation Log with the latest status and required cleanup path.

Success criteria review

❌ 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 ad2c still 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.

Next steps

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.

stm32f446re mikroişlemcisini kullandın mı

Thought for 2 sec

Read schematic.

Thought for a moment

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.
