Pixhawk PX4 Documentation
Note: Connects to POWER on PX4
Consult Ardupilot for your specific type of quadcopter and plug the ESCs into your Pixhawk's MAIN OUT channels 1-4 in the correct order.
This is a list of the absolute minimum number of parts you need installed to operate your vehicle safely in different modes.
To fly in Stabilize Mode (on a copter) or drive in Manual mode (on a rover) you will need...
- A Pixhawk with correct firmware and calibration uploaded
- A battery, typically a 3 cell (11.1 volts, 5100 milliamp-hours)
- BEC voltage regulator
- The appropriate number of motors for your vehicle
- The same number of ESCs as motors (Quad, Hex, Octo, etc etc -Copters only)
- A motor controller, such as a Sabertooth or a Kangaroo (Ground vehicles only)
- An RC receiver radio, preferably a DSMX or equivalent
- A RC transmitter that has been bound to the RC receiver
To fly in Loiter or Auto Mode, or drive in Hold or Auto Mode, you will need...
- All of the above
- A GPS
- A Compass (Your Pixhawk contains an internal compass.)
Use of a Buzzer and Telemetry equipment is optional, but highly encouraged, as they make debugging a lot easier (and safer!)
