Size and Pinout
Connecting to the Controller
- Connect to the flight controller’s CAN1 / CAN2 port (CAN1 is recommended).
Tip
The flight controller must support the DroneCAN protocol, such as ArduPilot and PX4 flight stacks.
Controller Parameter Setup
Before use, you need to configure the flight controller parameters to enable the Neo 4 Nano; the method varies depending on the controller firmware.
ArduPilot Firmware
In Mission Planner’s Full Parameter List, set the following parameters, write them, and then reboot:
CAN_P1_DRIVERset to 1.CAN_P2_DRIVERset to 1.NTF_LED_TYPESset to 231.GPS_TYPE/GPS1_TYPEset to 9 (if used as GPS1).
Using the LGC ground station, you can configure it quickly without manual parameter adjustment.
PX4 Firmware
In QGroundControl > Parameters, set the following parameters, write them, and then reboot:
UAVCAN_ENABLEset to Sensors Automatic config.UAVCAN_SUB_GPSset to Enable.
