SparkFun GPS NEO-M9N Hookup Guide
Introduction
The SparkFun GPS NEO-M9N is the next iteration of u-blox's GPS offerings! We've developed two flavors of the
board: one with a small chip antenna and another with a u.FL connector so that you can select an antenna of your
choosing.

Page 6: Hardware Overview
GPS Basics Serial Peripheral Interface (SPI) The Global Positioning System (GPS) is an SPI is commonly used to connect microcontrollers to engineering marvel that we all have access to for a peripherals such as sensors, shift registers, and SD relatively low cost and no subscription fee. With the cards. - Page 7 Battery The small metal disk in the upper left corner is a small lithium battery. This battery does not provide power to the IC like the 3.3V system does, but to relevant systems inside the IC that allow for a quick reconnection to satellites. The time to first fix will about ~29 seconds, but after it has a lock, that battery will allow for a two second time to first fix.
- Page 8 UART functions on those lines. For more information, check out our tutorial on working with jumper pads and PCB traces. Chip Antenna or U.FL Connector The SparkFun GPS NEO-M9N with Chip Antenna has a GNSS antenna near its left Qwiic connector while its cousin has a U.FL connector in which you can connect a patch antenna.
- Page 9 Chip Antenna U.FL Qwiic and I C There are two pins labeled which indicates the I C data lines. Similarly, you can use either of the Qwiic connectors to provide power and utilize I C. The Qwiic ecosystem is made for fast prototyping by removing the need for soldering.
- Page 10 UART There are two pins on the right most header labeled for their UART functionality. Broken Out Pins There are four other pins broken out: Pulse per second ( ), Reset ( ), Safeboot ( ), and finally the SAFE interrupt pin ( ).
- Page 11 GPS Capabilities The SparkFun NEO-M9N is able to connect to up to four different GNSS constellations at a time making it very accurate for its size. Below are the listed capabilities of the GPS unit when connecting to multiple GNSS constellations and when connecting to a single constellation.

Page 13: Example Code
For this example, I used a Qwiic capable RedBoard and associated USB cable. connecting the boards with Qwiic cable, the assembly is very simple. Plug a Qwiic cable between the RedBoard and the SparkFun NEO-M9N with chip antenna and that's it! Just as easily I could have used the version with the U.FL connector and plugged in one of our patch antennas to the GPS board. - Page 14 #include <Wire.h> //Needed for I2C to GPS #include "SparkFun_Ublox_Arduino_Library.h" //Click here to get the library: http://librarymanag er/All#SparkFun_Ublox_GPS SFE_UBLOX_GPS myGPS; void setup() Serial.begin(115200); Serial.println("SparkFun Ublox Example"); Wire.begin(); if (myGPS.begin() == false) Serial.println(F("Ublox GPS not detected at default I2C address.
