Insert SD Card
Insert your microSD card into your computer using an SD card reader. Make sure the card is empty or backed up - all data will be erased during flashing. It's recommended to format the SD card first using the official SD Card Formatter tool.

Open Balena Etcher, click 'Flash from file' and select the downloaded Stratux image. Select your SD card as the target, then click 'Flash!'. The process takes 5-10 minutes.
Verify and Eject
Etcher will automatically verify the flash. Once complete, safely eject the SD card from your computer. The card is now ready to use in your Stratux.

Insert the flashed SD card into your Raspberry Pi. Connect power and wait for the device to boot. You should see the 'stratux' WiFi network appear within 60 seconds.
Important Notes
- Always use a high-quality SD card (Class 10 or better) to prevent corruption
- The EU firmware requires different SDR calibration than US firmware
- Keep a backup of your SD card image after configuration
