I have the Sparkfun 7-segment(4 digit) serial enabled display working via I2C. I modified the sample code referenced on the product page and all worked as advertised. This is a 5v device, but no problems have been seen interpreting the 3.3v High logic level. It doesn't seem like a level converter will be necessary. The backpack enables internal pull-up resistors, so no external resistors were added.

I have drivers written for SPI and Serial also, but these have not yet been tested.


Update: SPI and Serial drivers have now been tested.
