Is there any difference between the currently advertised Leonardo and one advertised as "original Leonardo R3"?
Is this the one that you refer to as "currently advertised Leonardo"?
The "original Leonardo R3" is more than likely a clone as there is no genuine "Leonardo R3".
Clones can differ slightly from the genuine product in components used. Build quality can be excellent or crap. Functionality should be the same.
Yes! That is the one.
Thanks!
If you don't work through examples you don't understand, you never learn anything new.
The current Leonardo schematic on the Arduino store website listing for the Leonardo, in the documentation tab, is revision 3d.
