Fixing PCB Airwire Errors

flux

Work done
  • Reviewed the current floating-pin ERC findings on U1, U2, and U3.
  • Verified datasheet guidance for the flagged pins: U2 RESV19 is do-not-connect, RESV20 must connect to GND, AUX_CL and AUX_DA are optional auxiliary I2C pins, and U3 has multiple N.C. pins while its LED driver outputs are unused in this design.
  • Removed the broken prior no-connect marker components U9 through U26, which were themselves causing ERC errors.
  • Added explicit datasheet-based implementation notes on U1, U2, and U3 documenting which flagged pins are intentionally unused and how they should be handled.
Success criteria review
  • ❌ All intentional unused pins on U1, U2, and U3 are not yet correctly marked with an ERC-accepted no-connect designation.
  • ❌ The ERC report still shows 18 floating-pin errors on intentional unused MCU/sensor pins.
  • ✅ Documentation notes now clearly state the intended datasheet-based handling on U1, U2, and U3.
Next steps I removed the faulty marker components and documented the correct pin intent, but I could not complete ERC closure because the available schematic-editing tools in this environment do not expose a working operation for applying Flux's ERC-recognized no-connect designation directly onto existing pins. If that no-connect annotation becomes writable through the available tools, I can finish the remaining 18 floating-pin fixes and re-check ERC immediately.
