Thanks!
I’m trying to connect a hover (V1 http://www.hoverlabs.co/shop/hover-original) gesture control and have every pin needed on the Atmega for the hover but am missing a 3V+ line. Is there one somewhere on the backpack, like there is on an Arduino UNO?

To update this topic to the V2 backpack, since the onboard button was moved from pin 10 to pin 11 can I assume the unused digital pins are 10, 12, and 13?
And the analog pins are 4 & 5?
Thanks,
Erik

So I ended up using this serial adapter from Tinkersphere: http://tinkersphere.com/electronic-components/803-ft232-serial-module-ftdi-helper.html. It was weird I checked the voltage level on the TX pin on a number of their FTDI cables and all were in the range 2.8-3.0 and wouldn’t successfully upload a sketch. But this adapter works so I’m happy.

I just did some tests on the cable, following this http://www.ladyada.net/wiki/ftditest, and all pins checked out good except the TX pin measured 2.7v instead of 3.3v. Could that cause a problem with the serial comm?
