    Troubleshooting
    
          
      
            
    • Windows: Install WinUSB driver via Zadig if the device doesn't appear.
      • 
            
    • Browser: Must use Chrome or Edge on desktop over HTTPS. Safari & Firefox are not supported.
      • 
            
    • Cable: Use a direct USB port and a data-capable (not charge-only) cable.
      • 
            
    • Stuck in DFU? Power-cycle the module and retry from step one.
