Module GNSS
Description
Module GNSS is a multifunctional global positioning communication module, equipped with the NEO-M9N-OOB high-precision GNSS positioning module, supporting multiple satellite signal reception. It also integrates a six-axis attitude sensor BMI270, a three-axis magnetometer BMM150, and a barometric pressure sensor, enabling comprehensive measurement of location, angle, altitude, and other geographic information. The module has reserved expansion slots for the M5Stamp series, allowing for additional IoT communication functionalities. It is suitable for applications in positioning and navigation, agriculture, logistics, geographic surveying, environmental monitoring, and more.
Features
- Multiple Satellite Positioning: Supports multiple satellite systems (GPS, GLONASS, Galileo, and BeiDou) for precise positioning.
- High Precision: Positioning accuracy of approximately 1.5 meters.
- Multi-Signal Reception: Simultaneously receives four GNSS signals for more accurate positioning.

BMM150 Magnetic Field Interference
Products with magnets may interfere with the BMM150 magnetic field sensor, causing abnormal readings. When used with an M5 master control device containing a magnet, the magnet needs to be removed, and at the same time, the BMM150 sensor should be kept away from strong magnetic fields.
Signal Quality
To ensure good signal reception for the GPS module, place the module outdoors during use.
Reserved DIP switches and toggle switches allow for adjustments to serial port pins, PPS timestamp pins, and attitude sensor communication addresses.
Sensor I2C Address
The BMM150's I2C bus is connected to the BMI270. Note that the host cannot scan the BMM150's I2C address.
| Chip | ADDRESS |
|---|---|
| BMI270 ADDR | 0x69 |
| BMM150 ADDR | 0x10 |
| BMM280 ADDR | 0x76 |
