Im working on gps tracking system for heavy equipment. I started out project with Fona 3g from adafruit and raspberry pi. but now i just realized that raspberry pi will file sys will get corrupted from machine turning off and on and not having time for proper shutdown for pi. so im looking for better and cheaper solution to replace pi, that can handle unexpected shutdowns and not mess up. also if someone knows cheaper alternative to fona 3g, that has cellular and gps support, i would appreciate it.
