PCB Schematic Draft

flux

U1 is now a 6-pin placeholder with no assumed pinout. I’m updating the part notes so the uncertainties stay visible instead of encoded as guessed values.

flux

Applied the microscope-inventory corrections: U1 is now a 6-pin placeholder, R6/C1-C3/D1-D3 are annotated as uncertain, and possible R5 is documented as a note only.
Open items:
  • U1 pins are intentionally floating until trace mapping confirms pinout.
  • R6, R7, C1-C3, D1-D3 type/polarity, and possible R5 still need measurement/confirmation.
  • ERC still reports expected unresolved placeholder pins and missing MPNs for generic draft parts.
Updated files: Schematic Capture Notes and Project Specification.
Suggested next steps:
  1. Measure R6/R7 and C1-C3.
  2. Confirm D1-D3 with diode/LED test mode.
  3. Provide U1/U2 continuity maps so I can wire the placeholders correctly.
