Support Four Satellites u-blox M10 Satellite Receiver System
NEO 4 SE can receive four GNSS concurrently, supporting BeiDou, Galileo, GLONASS, and GPS/QZSS systems. The receiver can select the optimal signals to maximize location availability, allowing the GNSS module to perform well even in challenging environments such as urban canyons.
Precise Positioning Integrate Dual SAW + LNA
NEO 4 SE integrates TCXO, dual LNA architecture, together with an active receiving antenna composed of an RF filtering system, which can provide outstanding receiving sensitivity and acquisition time, effectively enhancing positioning accuracy.
High-Performance STM32H5 Processor Self-Developed M4C Architecture Software
It adopts brand-new STM32H5 Arm®-Cortex®-M33 CPU processor, running frequency up to 250 MHz, providing the system with stronger computing power. It runs the highly flexible M4C architecture software developed by CUAV, which can achieve customized development and upgrading efficiently.
Strong Anti-Interference Built-In ST IIS2MDC Electronic Sensor
Integrating new ST IIS2MDC electronic Sensor internally, NEO 4 SE has a magnetic field dynamic range of up to ± 50 Gs and integrates temperature offset compensation function. It has a high dynamic range and strong anti-magnetic field interference ability among similar products.
Adopt DroneCAN Protocol Compatible with Mainstream Open Source Platform
NEO 4 SE adopts the DroneCAN protocol and is compatible with ArduPilot and PX4 open source platform protocol stacks. It has a wide range of application scenarios and stronger expandability and flexibility.
Multi-Functional RGB Status Light Controller Disarming Switch
It is equipped with an 8-channel bus RGB light group, which can present multi-level and rich status effects. It is linked with a built-in buzzer in multiple frequencies, and generate a variety of recognizable states through intelligent scene recognition, covering various work modes such as controller disarming switch, battery level, positioning, fault, etc.
