I’ll add an ESP32 NodeMCU module as the external UART endpoint, move the existing PA9/GND connections from the simple header to it, then switch to schematic view and tidy the schematic layout for readability.
Added the ESP32 external module as U3 (ESP32-DEVKIT-V1), connected Nucleo PA9 → U3 D4/GPIO4, and tied both ESP32 GND pins to the common GND net. I also removed the temporary 2-pin ESP32 header and updated the firmware notes to reference U3.

I could not continue with schematic-view switching/reorganization because your account currently has no available ACUs, so AI execution is paused.
The exact “ESP32 NodeMCU” part was not available; I used the available ESP32 DevKit-style module.
Next steps
Add ACUs, then ask me to reorganize the schematic visually by functional blocks.
Run ERC again after cleanup.
If you need the exact NodeMCU footprint/module, we can import or create that component.
