Diagnosztikai Eszköz Készítése

flux

Cél: elkészíteni a diagnosztikai eszközödet.
Rövid terv:
  1. Követelmények tisztázása. 2) Rendszerarchitektúra kiválasztása. 3) Kapcsolási rajz és támogató áramkörök. 4) PCB-előkészítés és elrendezés. 5) Ellenőrzés, BOM és gyártási fájlok.
Kérlek pontosíts:
  • Mit szeretnél mérni/diagnosztizálni (jelek, szenzorok), milyen tartományokkal és pontossággal?
  • Milyen interfészek kellenek (USB, UART, BLE/Wi‑Fi), lesz kijelző vagy gomb?
  • Tápellátás és fizikai korlátok: USB/akku, méret/borítás, környezeti követelmények?
Ha megvannak a válaszok, összeállítom a végrehajtható tervet; a futtatáshoz a tervsávon kattints a Start gombra.

Ehez tegyunk egy Usb c csatlakozot

flux

Cél: USB‑C csatlakozó hozzáadása a projektedhez.
Terv:
  • Hozzáadok egy USB Type‑C Receptacle csatlakozót a kapcsolási rajzhoz (USB 2.0 eszköz/UFP).
  • Beállítom a designatort (pl. J1) és az alap tulajdonságokat.
  • Huzalozás és kiegészítők később.
Pontosíts kérlek: SMD vagy furatszerelt? Egyenes (right‑angle) vagy függőleges? USB 2.0 elég? Megjegyzés: később tegyünk bidirekciós, vonalanként 1 pF alatti TVS védelmet a D+/D‑ vonalakra.
Választás csatlakozó típusról
Kérdés CC ellenállásokról
