Moruk sadece yolları çizdim, komponent yeri/şematik/BOM değiştirmedim.
Yapılan route’lar:
- DB25 +12V → fuse ve VBAT_PROT giriş hattı
- DB25 tarafında CANH, CANL köprüleri, K-Line köprüleri, L-Line
- USB-B’den ESD’ye D+ / D-
- 5V / 3V3 buck çıkışlarının bir kısmı
- U2/U3 SW hatlarının bir kısmı
- RX/TX LED seri kısa yolları
Son durum:
- Airwire hâlâ var: yaklaşık 151 DRC airwire/error
- Dangling/floating/invalid-layer raporda görünmedi
- Kritik blokaj: U1 STM32 pinlerinden çıkan yolların çoğu mevcut komponent yerleri sabitken no-path veriyor; özellikle USB ESD→MCU, CAN TX/RX, K-Line TX, I2C, SWD, GPIO breakout hatları.
Kart şu haliyle baskıya hazır değil; yolların tamamlanması için U1 çevresindeki komponentleri oynatmadan router yetmiyor.
U1 çevresindeki parçaları gerektiği kadar oynat, yolları tamamen bitir ve DRC çalıştır.

Moruk U1 çevresini açtım, GPIO headerları sağ tarafa taşıdım, D2/U4/U5/U6 çevresini route edilebilir hale getirdim ve ana hatların çoğunu çizdim: USB D+/D-, CAN TX/RX + CANH/CANL, K-Line TX/RX + K/L çıkışları, SWD, I2C, VBAT/fuse/TVS/buck giriş, 5V/3V3 bazı güç yolları.
Açık kalanlar:
- Kart baskıya hazır değil.
- Final DRC’de hâlâ 184 airwire/error var.
- Dangling trace / invalid layer / component outside board görünmedi; ana problem kalan bağlantıların route edilmemiş olması.
- Özellikle GPIO breakout, bazı MCU power/decoupling, BOOT0, bazı buck lokal hatları ve birkaç support net hâlâ açık.
Sonraki adımlar:
- Kalan airwire’ları daha küçük bloklar halinde route etmek.
- BOOT0/R5/R_BOOT çevresini tekrar elle yaklaştırıp bağlamak.
- Buck lokal devrelerini tek tek temizlemek.
- En son DRC temizlenince Gerber export’a geçmek.
Route and verify all
Fix BOOT0 first

Notes
- Supplier part numbers are filled where the library component already carried an LCSC number. Generic passives now have manufacturer MPNs but do not yet have supplier SKU fields assigned.
- The inductor footprints/values were not changed per instruction. Verify the selected inductor MPNs against the final assembly house AVL before ordering, especially current rating versus the existing 0603 footprint constraint.
