Product description: GPS module NEO-M9N - built-in antenna - Qwiic - SparkFun GPS-15733.
NEO-M9Nhigh quality module with92 channelGNSS receiver and built-in antenna. It allows to receive signals fromGPS,GLONASS,BeidouandGalileowith an accuracy of1.5 m. It can process4 readingsat the same time, so it can precisely determine the position even in difficult conditions. For communication it usesUART,SPIandI2Cinterfaces, and built-inQwiicconnectors allow to connect the board with other elements without the need ofsoldering. In addition, the module has leads to which it is possible to soldergoldpinconnectors in case of a project witha prototype board. On the board there is a lithiumRTCbattery, which reduces time-to-first-fix. Power supply voltage is3,3 V.
