I am using UNO with Mega Moto Plus. But realized that I need more UART ports. Zero looks like a good option and I was wondering that can I interface Mega Moto with out any problems regarding hardware and software point of views.
Mega Moto's data sheet is as follows
I was also wondering what are the differences in the ways that both boards get programmed via Audrino's IDE. I am planning to put the SAM21G on my own board and what implications should I expect.
