Hardware Setup

Wiring

The ARK GPS is connected to the CAN bus using a Pixhawk standard 4 pin JST GH cable. For more information, refer to the CAN Wiring instructions.

LED Meanings

You will see green, blue and red LEDs on the ARK GPS when it is being flashed, and a blinking green LED if it is running properly.

If you see a red LED there is an error and you should check the following:

• Make sure the flight controller has an SD card installed.

• Make sure the ARK GPS has ark_can-gps_canbootloader installed prior to flashing ark_can-gps_default.

• Remove binaries from the root and ufw directories of the SD card and try to build and flash again.
