I am trying to design a new arduino Mega board, for standalone applications.
On doing this redesign i would like to remove all USB related components in the actual Mega board. So the idea was to have some SIL terminals in the new board where i could plug in the other block (ATMega8U2) that would help me to program the ATMega 2560.
Is this possible? What is the way to go when trying to build standalone devices with arduino?
