ArduPilot Project

Getting the source

You can either download the source using the "ZIP" button at the top of the github page, or you can make a clone using git:

git clone git://

Building using Arduino IDE

ArduPilot is no longer compatible with the standard Arduino distribution. You need to use a patched Arduino IDE to build ArduPilot.

  1. The patched ArduPilot Arduino IDE is available for Mac and Windows from the downloads page. On Linux, you should use the makefile build.

  2. Unpack and launch the ArduPilot Arduino IDE. In the preferences menu, set your sketchbook location to your downloaded or cloned ardupilot directory.

  3. In the ArduPilot Arduino IDE, select your ArduPilot type (APM1 or APM2) from the ArduPilot menu (in the top menubar).

  4. Restart the ArduPilot Arduino IDE. You should now be able to build ArduPlane or ArduCopter from source.

  5. Remember that, after changing ArduPilot type (APM1 or APM2) in the IDE, you'll need to close and restart the IDE before continuing.

Building using make

  1. Before you build the project for the first time, you'll need to run make configure from a sketch directory. This will create a file at the top level of the repository. You can set some defaults in

  2. In the sketch directory, type make to build for APM2. Alternatively, make apm1 will build for the APM1.

  3. Type make upload to upload. You may need to set the correct default serial port in your
