Apart from the Reset, Force Recovery and Power on buttons, Apollo also features two user programmable inputs, one of the buttons by default is set to "One-Key Recovery", enabling you to easily reflash or restore Apollo to its default. The second button is not configured to let you add your own application.

At startup, Apollo automatically checks whether a new firmware update is available. If there is, the user is prompted on
the OLED display to confirm if they wish to upgrade Apollo to this new release, or to skip the update. If it is
confirmed, Apollo automatically downloads and applies the upgrade, and the user is prompted to reboot the Apollo board
