In this video lesson we will connect the Adafruit Ultimate GPS to the Raspberry Pi Pico W, and will write a simple program to capture the data being sent by the GPS. In this lesson, we simply want to read and print the NMEA sentences coming off the GPS, and then in future lessons we will begin to parse the data, and turn the data into usable numbers. This is the schematic for connecting the GPS to your Raspberry Pi Pico W.
Then this is the simple code we developed to allow reading the data coming from the GPS.
