Here’s the summary:
Work done
Unable to do
  • I can’t automatically verify capacitor placement near U3; please confirm that C8–C11 remain on 3V3 and are positioned adjacent to U3.
Success criteria
  • ✅ U3 is present and powered
  • ✅ UART & reset are correctly wired
  • ✅ Battery positive flows via SW1; 5V net is disconnected
  • ℹ️ 3V3 decoupling caps retention: manual confirmation needed
Next, would you like to review the PCB layout orPosition the decoupling caps around U3?
