Based on knowledge base guidance, when substituting a module you should preserve its pin-to-net assignments exactly and verify power/ground rails remain intact.

Next steps:

Shall I proceed to locate “ESP8684-WROOM-07-H2” in the library and apply the replacement?

I’m not seeing the module’s pin-assignment table or footprint dimensions in the PDF you uploaded, which I need to verify that the WROOM-07-H2 is truly a drop-in for your current footprint. Could you point me to the page or section title where the pin mappings (or pin-definition table) are listed, or paste that table here? Once I have that, I can confirm compatibility and proceed with replacing the module in your design.

@file extract the mechanical dimension specifications from the PDF so I can confirm footprint outline.

I wasn’t able to extract any mechanical-outline text from the PDF—those drawings are likely embedded as images. Could you let me know which page the module outline appears on, or paste the key dimension table (width, length, height and pin-pitch) here? With that I can confirm footprint compatibility.
