Maybe yet another logger. And maybe I am using old school components. For me this project is for learning and it will be the contributions of the people who give me feedback and me the person who will try to implement the feedback. I hope we can make it work ;-)
I have something working but I want to buffer the GPS string in an EEPROM and flush it to MMC at some periods of time.
This schematic I still do not have working...
I am trying something different. This solution is freezed.
