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 high-precision 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.

Features

  • U-blox M10Q Satellite Reception System
  • Self-developed highly flexible M4C architecture
  • STM32H5 high-performance processing unit
  • SAW+LNA dual filtering; stronger anti-interference ability
  • ST IIS2MDC electronic compass, strong anti-magnetic interference
  • Multi-function RGB full-color status light
  • DroneCAN standard protocol, high real-time performance, and strong anti-interference
  • Compatible with ArduPilot and PX4

Size and Pinouts

purchase

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 setting method varies depending on the flight controller firmware.

ArduPilot

Set the following parameters in the Mission planner’s All Parameters table and restart after writing:

  • CAN_P1_DRIVER is set to 1.
  • CAN_P2_DRIVER is set to 1.
  • NTF_LED_TYPES is set to 231.
  • GPS_TYPE/ GPS1_TYPE is 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_GPS is set to Enable.
