I currently have a project that is working on an AtMega2560 platform (heavily derived off the Arduino Mega). It mainly involves a GPS module and SD card.
Going forward I am looking to add a few more sensors (IMU etc.). I would like to a more powerful microcontroller -- for the high rate logging I need and also it seems best from a future scalability perspective.
I would like to start with using one of the ARM based uC platforms available out there, transition my software to it using a breadboard setup, and then eventually make a custom board.
So my QUESTION is: Which would be an easier option from a migration/transition and community support point of view --- Teensy or Due? I currently use the SDFat and Adafruit GPS libraries, the SDFat being a major concern for migration.
Any other considerations/suggestions/advice will be appreciated.
