Product description: Gravity - GNSS GPS receiver module BeiDou - I2C / UART - DFRobot TEL0157
GNSS GPS BeiDou receiver module with Gravity connector manufactured by DFRobot. The GNSS positioning module supports positioning of both single and multiple systems. Works with BeiDou , GPS , GLONASS and other multi-satellite systems . It is characterized by higher precision and faster speed than traditional single GPS positioning. It provides highly precise position data such as longitude, latitude, altitude and current time, even in complex urban environments. The module is compatible with Arduino, ESP32 and Raspberry Pi.
Gravity - GNSS GPS receiver module BeiDou - I2C / UART - DFRobot TEL0157.
The plate has four holes for easy assembly and disassembly.
Satellite navigation - what is GNSS?
GNSS is the global navigation system of Global Navigation Satellite Systems, which covers the entire Earth. Its main task is to determine the user's position. The GNSS systems also include the GPS Global Positioning System and GLONASS. Wondering how satellite navigation works? It's simple - as a type of radio navigation, it uses radio waves that are broadcast from artificial satellites to determine the location of points and moving receivers along with the parameters of their movement on the Earth's surface.
Suggested use of the module
- Driving and flying vehicle navigation
- Handheld positioning tracker
- Item tracking
- Smart weather station
Pinout description and connection diagram
The module supports two communication interfaces - I2C and UART. The user can choose the method of communication depending on the project needs. Connect the pins according to the dependence below:
- D / T - I2C bus data line / UART bus transmitter
- C / R - I2C bus clock / I2C bus receiver line
- "-" - GND - system ground
- "+" - VCC - board power pin
For more information on connecting the module, see the user's guide .
