NEO 4 Dustproof and Waterproof GNSS

NEO 4 is a general-purpose satellite navigation receiver module with a two-shot over-molded integrated design and IP67 dustproof and waterproof protection. It integrates the u-blox M10 satellite receiver system, supports concurrent reception of signals from four major positioning systems, and is equipped with a high-performance STM32H5 processor and an ST IIS2MDC electronic compass, delivering accurate positioning and excellent anti-interference and environmental adaptability. It supports an RGB full-color status indicator, uses the CAN bus protocol, and can be widely used in various unmanned system devices.

NOTE

ArduPilot and PX4 open-source platforms support NEO 4.

NOTE

NEO 4 supports two mounting methods: direct attachment and injection-molded bracket mounting. NEO 4 is designed to the IP67 protection rating (except for the CAN connector); if you need full IP67 protection, install it on a vehicle that can withstand water immersion, otherwise water may seep in from inside the vehicle through the CAN connector. You can also seal the CAN connector / injection-molded bracket channel to allow installation in a non-waterproof vehicle.

Hardware Installation Video

Controller parameter settings

Before use, you need to set the controller parameters to enable NEO 4; there are different setting methods depending on the controller firmware.

ArduPilot firmware

Set the following parameters in all parameter tables of Mission planner and restart after writing:

• CAN_P1_DRIVER set to 1.
• CAN_P2_DRIVER set to 1.
• NTF_LED_TYPES set to 231.
• GPS_TYPE / GPS1_TYPE set to 9 (as GPS1).

You can realize quick configuration without parameter adjustment via the LGC Ground Control Station.

PX4 firmware

Open QGroundControl>Parameters window, modify the following parameters and restart after writing:

• UAVCAN_ENABLE set to Sensors Automatic config.
• UAVCAN_SUB_GPS set to Enable.
