  • I have a question about powering the Arduino Pro. Is it okay to have external power and the FTDI Basic connected to the board at the same time? On the Uno board there is a circuit that switches the power to the external power if it is present. Looking at the Arduino Pro schematic I didn’t see such a circuit, but I may have over looked it. I think that there have been times that I have had both connected in the past, without a problem, I am wondering if I have just been lucky so far and I should avoid doing it?

  • Any idea when these will be in stock?

No public wish lists :(
