Qwiic GPS Dead Reckoning Breakout - GPS module with NEO-M8U system (U.FL connector)

Description

GPS module with 72-channel GNSS NEO-M8U receiver. The system can receive data from all major positioning systems: GPS, GLONASS, Galileo and BeiDou. Determining the position with the help of the module allows you to achieve an accuracy of up to 2.5 m. The module uses Untethered Dead Reckoning (UDR) technology, which provides a very accurate and continuous position by using the IMU sensor and GNSS measurements without having to connect the system to the vehicle. Provides position accuracy in cities or in covered areas. Continuous positioning is ensured even under low signal conditions and is available in the event of total signal loss (e.g. short tunnels and garages).

The module has a Qwiic connector with an I2C interface. Additionally, for users who do not work with the Qwiic system, UART, I2C and SPI interfaces were provided on pins with a 2.54 mm raster. There is also a socket on the board with a battery supporting the voltage, which significantly accelerates the start of the device after a momentary power failure.

The module is configured via a USB connector and a dedicated u-center application. The module is also available with the Arduino library with numerous examples of use.
