USB-C to SD Card Schematic
Finish off the project as you were going to.
Thought for 49 sec
You want the USB‑C PD pass‑through SD‑card reader schematic finished and ready for layout; the implementation plan for that is now complete and ready to run.
At a high level, executing the plan will:
- Finish and verify the PD sink/source and VBUS power‑path around U1, U2, and U3 so J2 reliably provides 5 V/3 A to J1 with protection and sense resistors sized safely (within 75% of rated power).
- Complete required support passives and ties for all ICs: U1, U2, U3, U4, U5, U6, J3, and ESD parts D4, U7, U8, using the datasheets plus 22–33 Ω series terminations on USB lines and 10 µF/0.1 µF decoupling where still needed.
- Lock down the USB 3.x data path: confirm J1 TX1±/RX1± → U4 → U5, and D+/D‑, with ESD arrays inserted correctly and no missing pulls or straps on configuration pins.
- Add practical test points on VBUS in/out, 3.3 V from U6, ground, and at least one HS and SS pair near J1/U4/U5, then run ERC and clean up any remaining issues.
To actually have me carry out those steps on your schematic, click “Start” on the plan bar in Flux; that will execute the plan and finish wiring/tuning the schematic for you. If you’d like, I can then review the completed schematic or help you define the key layout rules for the USB 3.x and PD sections next.
