It should be mentioned in the product text that the device is unusable without buying connectors, which aren't stocked by Sparkfun :-/

FWIW I wrote a Python3 interface for this, works on my RasPi: https://github.com/AKAMEDIASYSTEM/py-tca9534

Nope, it's because interacting with you is a waste of my time. Goodbye!

I've edited this post only because I'm not able to delete it. I wish to delete it because I'm not interested in spending more time on this.

I'd love to see usable documentation for this product, since it's a much-needed non-Uno shield.
Some basic questions with no obvious (spelled out in the product description) answers:
In what orientation does this mount to a Pro Mini?
What is the pinout for this product? (It's ambiguous and time-consuming to try to match the schematic to the product, and not everybody wants to open up Eagle to figure out how the schematic and the board match up)
What, exactly, is different between this product and the IDEO page you link to? I appreciate you linking to inspiration/designer's page, but in this case the ambiguity between what this does and what the IDEO item does is unhelpful.
While I love the idea behind this product, it's by far the worst-documented and most time-consuming thing I've ever purchased on Sparkfun.

I guess there's a budding numismatist at Sparkfun? http://en.wikipedia.org/wiki/Proof_coinage

I like this shield but it would be great to have a version that left pin 3 available (the way the original shield did) to be used as an interrupt pin for counting motor encoder ticks.
(Although, having said that, I'm having trouble counting ticks fast/accurately enough, does anyone have any resources to help me count ticks quickly?)

Has anyone actually found the appropriate couplers on mcmaster? I can't find anything that's metric and smaller than 10mm...

Careful - even though these are 2-axis accelerometers, they come on a breakout board with a pinout for a third axis (Z).
If you work in a lab that stocks both the 2- and the 3-axis versions, mark the 2-axis ones with a Sharpie to avoid some irritating debugging...
