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.
