Завершение Трассировки

flux

Заменил оба WT32-разъёма на MX1.25-compatible вертикальные кандидаты:
  • J4 заменён на WAFER-MX1.25-7PCB — 7 pin, MX1.25-compatible.
  • J5 заменён на 1.25T-8P-WV — 8 pin, 1.25 mm vertical-style/MX1.25-compatible.
Важно: замена компонентов уже выполнена, но из‑за механики замены в Flux соединения J4/J5 были уничтожены и ещё не восстановлены, а новые разъёмы ещё не размещены на PCB. На этом шаге закончились кредиты, поэтому я не смог завершить rewiring/placement/DRC.
Что нужно сделать дальше:
  1. Восстановить цепи:
    • J4: pin 1 → 5V, pin 7 → GND, остальные reserved/NC как раньше.
    • J5: pin 1 → 5V/VIO, pin 2 → GND, pin 3 → STEP, pin 4 → EN, pin 5 → TCRT_OUT, pin 6 → SCL, pin 7 → SDA, pin 8 → DIR.
  2. Проверить реальные pin names у новых J4/J5, потому что Flux показал нестандартный порядок пинов:
    • J4 pins: 1, 4, 8, 7, 6, 9, 5, 2, 3
    • J5 pins: 5, 10, 8, 2, 6, 3, 9, 1, 4, 7
  3. Разместить J4 снизу-слева, J5 снизу-справа.
  4. Запустить DRC/ERC и только потом продолжать трассировку.
