NEO 4 SE GNSS Module: Key Specs & Hardware Integration
NEO 4 SE is a high-performance single-point positioning module for unmanned systems. It integrates Ublox’s tenth-generation centimeter-level GNSS receiver, high-performance STM32H5 processor, electronic compass, safety switch, RGB full-color status light, supports DroneCan protocol, and is perfectly compatible with ArduPilot/PX4 firmware.
Note
The NEO 4 SE is fully supported by ArduPilot firmware 4.0 and higher.

Size and Pinouts
Hardware connection
- Connect neo 4SE to the CAN1/CAN2 interface of the smart controller (CAN1 is recommended)
Tip
The rest of the ArduPilot/PX4 flight stack setup is the same.
Flight control parameter settings
You need to set the flight controller parameters to enable Neo 4SE; the method varies by firmware.
ArduPilot
Set the following parameters in the Mission planner’s All Parameters table and restart after writing:
CAN_P1_DRIVERis set to 1.CAN_P2_DRIVERis set to 1.NTF_LED_TYPESis set to 231.GPS_TYPE/GPS1_TYPEis set to 9 (if used as GPS1).
PX4
In the QGroundControl>Parameters window, set the following parameters and reboot after writing:
UAVCAN_ENABLEis set to Sensors Automatic config.UAVCAN_SUB_GPSis set to Enable.
