Should I connect the Portenta H7 to bare sensor ICs or to ready-made breakout modules? This changes the required regulators, decoupling, pull-ups, footprints, and wiring.

I’ll treat that as bare BMP388 and ICM-42688-P ICs, connect both to the Portenta H7 over a shared 3.3 V I²C bus, and add the required decoupling, pull-ups, address configuration, and interrupt connections. This requires Agent mode; since this project is view-only, I’ll create an editable fork before building and verifying the schematic.

I confirmed the intended direction: use bare BMP388 and ICM-42688-P sensors with a Portenta H7, sharing a 3.3 V I²C bus and adding the required decoupling, pull-ups, address configuration, and interrupt connections.

No project changes were made. The source project remains view-only and still needs to be forked, then the components added, wired, and verified. Execution stopped because your ACUs ran out.
