Hello! Just joined this awesome project! 
I'm having an error, don know if I should post it here or open a thread with it.
I will report it, if you think may be a new thread is needed please tell me.
Ok, I created a sketch by uploading an existing one I had in my PC.
I connect the board, a Nano v3 from ebay.
I check "Verify" and it gives me "avr-g++: error: missing argument to '-mmcu='".
My question is, does this only works with official boards? I have them, but not right here with me to test it.
Thank you.
