M5Stack M135 GNSS Module is a global positioning wireless communication module that is compatible with multiple satellite positioning systems. This module features the NEO-M9N-00B GPS module and offers an accuracy of approximately 1.5 meters. The M135 GNSS module can simultaneously receive signals from four GNSS sources to ensure fast lock times and high precision. This module incorporates a BMM150 three-axis magnetometer, a BMI270 six-axis attitude sensor, and a barometric pressure sensor to measure the position, orientation, and altitude.
The M135 GNSS module can integrate the M5 Stamp wireless communication for remote IoT communication. This module offers customizable settings like serial port pins, PPS sync signal pins, and communication addresses for the attitude sensor. The M135 module includes an external MCX antenna interface, a button battery, and an EEPROM chip to store data during power loss. This module is used in applications such as agriculture, positioning and navigation, geospatial surveying, logistics, environmental monitoring, and emergency response.
