Hello - I have an Adafruit Screw Shield R3 that is currently sitting on top of an Ardiuno Duo, but I'd like to swap the Ardiuno Duo for a Teensy for easier interfacing to X-Plane (pots and switches).

I'd like to confirm that I can install a Teensy 3.2 into the Sparkfun Teensy Arduino Shield Adapter (KIT-13288) and then install the Adafruit Screw Shield R3 onto the Sparkfun Shield adapter.

I have reviewed the pinouts of the Sparkfun and Adafruit parts and it looks like they will correctly mate together, I was just concerned about 3.3V and 5V issues with this pairing.

Note that I am just planning on providing power to the Teensy via USB.

Thanks,

Charles
