I made this project to check distance trip and max speed of my truck model. GPS gets coordinates and checks position writing on SD card data log.csv. You can se tup a speed limit with a led alarm or a buzzer. SD card log.csv can be read with open office. Anyway you can easily modify it in log.txt in my GPS. I have add a reset button and a red BEC plug for external battery. Normally I power it from USB socket. Altitude needs 3D fix for better result. You can config NEO6M GPS (or better GPS) from "u-blox center".
