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.
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.
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.
Integrating the new ST IIS2MDC electronic compass internally, the NEO 4 SE features a magnetic field dynamic range of up to ±50 Gs and incorporates a temperature offset compensation function. It has a high dynamic range and strong anti-magnetic field interference ability among similar products
NEO 4 SE adopts the DroneCAN protocol and is compatible with the ArduPilot and PX4 open source platform protocol stacks. It has a wide range of application scenarios and stronger expandability and flexibility.
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 generates a variety of recognizable states through intelligent scene recognition, covering various work modes such as controller disarming switch, battery level, positioning, fault, etc.
