Has anyone used these 3 together with success? Fairly new to using the Mega and need to know if there are known issues (code wise or hardware wise) before I purchase and begin work. The project is a 4-line LCD display that will show number of satelites, Fix, Latitude, Longitude, Compass direction, but not speed or altutude. Thoughts about which libraries to begin with.
Most all GPS have a standard output format and the TinyGPSplus library will decode the data from an M8N.
However most all GPSs use 3.3V signal logic levels but the Mega uses 5V logic levels so you will need to use logic level conversion circuits. Lots easier to use a 3.3V logic Level micro controller
Thank you. Thats good info. I had chose the mega because I needed multiple serial ports and wasnt shure if the nano was beefed up to handle that.
Is there an example that I could use for a logic level conversion circuit in this project?
Yes. Thank you.
