GNSS Module is a global positioning wireless communication module featuring the NEO-M9N-00B GPS module. Compatible with multiple satellite positioning systems, it offers an impressive accuracy of approximately 1.5 meters. This module can simultaneously receive signals from four GNSS sources, ensuring high precision and fast lock times. Equipped with an external MCX antenna interface, it also includes a button battery and an EEPROM chip to securely store data in case of power loss.
In addition to its exceptional positioning capabilities, the module integrates mutible sensors for comprehensive geographic information measuring. It incorporates a BMI270 six-axis attitude sensor, a BMM150 three-axis magnetometer, and a barometric pressure sensor. This combination enables precise measurement of position, orientation, altitude, and other essential parameters. Furthermore, the module offers flexibility through its provision of DIP switches and toggle switches. These allow easy adjustment of serial port pins, PPS pins, and communication addresses for the attitude sensor.
Designed for seamless communication with M5Stack controllers, the GNSS Module utilizes M5BUS for data exchange and supports adding M5 Stamp wireless communication modules, which empowers remote IoT communication, making it a versatile solution for applications such as positioning and navigation, agriculture, logistics, geospatial surveying, environmental monitoring, and safety and emergency response.
