PX4 System Defaults

The following describe the system defaults, as specified by boards/modalai/fc-v1/init/rc.board_defaults

MAVLink Instance 0

• configured by default as TELEM1 (exposed atJ1010) at 57600 baud in Normal mode
• this is configurable by the user

MAVLink Instance 1

• hard coded to TELEM2 as it’s routed in the PCB, defaulted at 921600 baud in Normal mode
• this is the primary serial interface to communicate with VOXL
• the baud rate and mode are configurable by the user, but recommended to use the defaults

Safety Switch Disabled

The saftety switch can be ‘pressed’ by pulling J1011 pin 5 up to 3.3V (which is provided by J13 pin 1). By default, we have the safety switch disabled, but it can be enabled via QGroundControl by setting CBRK_IO_SAFETY to 0.
