Reading logs via the Dev Board
The Developer Board allows you to read Flipper Zero logs via UART. Unlike reading logs via the command-line interface (CLI), the Developer Board enables you to collect logs from the device directly to a serial console independently from the operating system of Flipper Zero. It allows you to see the device's logs when it's loading, updating, or crashing. It's useful for debugging and troubleshooting during software development.
Depending on your needs, you can set the log level by going to Main Menu -> Settings -> Log Level. To learn more about logging levels, visit Settings.
Depending on your operating system, you need to install an additional application on your computer to read logs via the Developer Board:

To quit, close the minicom window or quit via the minicom menu.
