5 Connect modules to Pixhawk
Connect the buzzer, switch, splitter,
GPS, power, and telemetry modules
to Pixhawk.
To ensure the most secure cable
assembly, thread the cables through
the holes in the plates where
possible. Where the cables dangle
away from the frame, such as along
the mast, use zip ties to secure the
cables to the frame.
Note: Pixhawk’s DF13 connectors
can be fragile when disconnected
and reconnected multiple times. Do
not pull on the cables to disconnect,
use a fingernail or small, flat tool to
loosen the edges of the connector
until it pops out.
Buzzer and switch: Connect the buzzer to Pixhawk’s BUZZER port, and connect the switch (safety
button) to the SWITCH port. These components are mandatory for Pixhawk.
I2C splitter: Connect the four-wire cable to one of the ports on the splitter and to Pixhawk’s I2C port.
GPS with compass: Use the long cables provided with the GPS mast to connect the GPS with
compass module to Pixhawk. Connect the four-wire cable to the GPS’ MAG port and to one of the
ports on the I2C splitter. Connect the six-wire cable to the GPS port on the GPS module and to
Pixhawk’s GPS port.
Power module: Connect the six-wire cable (red and black cable protruding from the central space in
the top plate of the copter) to Pixhawk’s POWER port.
Telemetry radio: Connect the six-wire cable to a telemetry radio module and Pixhawk’s TELEM 1 port.
