ESP32-H2 Relay Board Overview

I couldn’t find any Flux documentation that explains why the Plan bar’s Start button can be disabled. You can review the general Execution Plan overview here:

implement the plan
You want me to implement the fix-and-hardening plan for this project. Here’s the plan I’ll run:
  1. Gather ERC/DRC results and triage issues.
  2. Schematic fixes: add a flyback diode on K1, complete LDO decoupling on U2, verify U4 drive and R1, ensure U1 EN bias.
  3. Verify nets and labels (12V, 3V3, GND).
  4. Re-run DRC; flag HV/LV creepage risks; adjust board size if needed.
  5. Re-run reviews, update BOM, and prep exports.
Click Start on the plan bar to execute. Let me know if you want any changes.
Run ERC/DRC review
Add flyback diode
Check AMS1117 decoupling
Verify key nets
