Actually, $2.68 for an ADXL345 breakout board.
I bought - and eventually received - two of these and they work, at least to the extent I worked with them at room temperature. The board's lengthwise pin spacing is odd, though, 0.95" instead of 1.0". Is it likely that the ADXL345 itself is a legitimate part that found itself on a board layout error too late - or are they likely counterfeits or out-of-spec? How is this possible? http://www.ebay.com/itm/170934206455
