I am planning to buy an Arduino MEGA ADK
But saw the there are two versions of it available on a few online stores.
So would just like to know what is the main difference between Arduino MEGA ADK R2 and R3??
And considering the 7$ - 10$ cheaper price tag of an Arduino ADK Revision 2 (R2) on a few websites, is it actually worth paying more for an R3?
Also has anyone used the ADK and has it been more useful and productive? Or do you suggest buying a MEGA 2560 R3 instead…
Thankx in Advance for the Advice
