I would like to make my Arduino project based on Mega 2560 to an Breadboard for prototyping like this exemple with Arduino UNO :
the circuit "Mega2560" is so small that it must add an expander or some thing like that for to be able to fit it into a breadboard !.
Something like this?
Thx CrossRoads for your help,
But how i can use this card with a classic breadboard ?! "I mean solderless"
The problem with the Atmega 2560 is that it has an awful lot of pins so you would need a loooong breadboard.
I guess you could make an adapter between @CrossRoads' board and a linear pin layout with some veroboard and a lot of patience.
Ok Thank you for your help :)
