DSU7 is an interface for AeroFC naming, which includes FMU SWD and UART7 interfaces. UART7
is used as the DEBUG interface for AeroFC with PX4 firmware. Whereas when running ArduPilot
firmware; UART7 is used as the communication serial port and USB is used to debug the output.
The PPMIN interface is limited to powering the RC receiver and cannot be connected to any
power/load.
Voltage Ratings
AeroFC AutoPilot can be triple-redundant on the power supply if three power sources are
supplied. The two power rails are:
POWER1
,
POWER2
and
USB
.
The output power rails
FMU PWM OUT
and
I/O PWM OUT
(0V to 36V) do not power the flight
controller board (and are not powered by it). You must supply power to one
of
POWER1
,
POWER2
or
USB
or the board will be unpowered.
Normal Operation Maximum Ratings
Under these conditions all power sources will be used in this order to power the system:
1.
POWER1
and
POWER2
inputs (4.3V to 5.4V)
2.
USB
input (4.75V to 5.25V)
Debug Port
The system's serial console and SWD interface operate on the
FMU Debug
port. Simply connect
the FTDI cable to the Debug & F7 SWD connector (the product list contains the FTDI cable). It
does not have an i/o debug interface.
