SparkFun GPS NEO-M9N Hookup Guide
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. If you need tips on plugging in the U.FL connector, then check out our U.FL tutorial. If you're going to be soldering to the through hole pins for I2C functionality, then just attach lines to power, ground, and the I2C data lines to a microcontroller of your choice.
For a secure connection with an external antenna, we recommend using the SMA version.
