Main components and all support passives are now in the schematic. I’m wiring

ERC found one real schematic-library conflict: the selected VQFN buck part marks its NC pad as no-connect even though the datasheet says to tie that pad to SW. I’m switching to the HSOIC LMR33630 variant with no NC pad so the schematic can verify cleanly.

Considering U3 Replacement
I think I could replace the current component with HSOIC, omitting U3. It seems I need library support for U3, and I may be able to remove the existing U3 and add the same designator instead. I'll edit the schematic next and inspect the pins. However, U3 might still play a role, so I'll need to consider disconnecting it. Once I add the new U3, I must connect its pins to the existing nets while keeping passive components intact.
The response is taking longer than expected.
