All pins from the IC are broken out to standard 0.1&quot; spaced headers. The Serial in and out pins are on opposite sides of the board with the remaining pins carried over so that multiple shift register boards can be chained together.</p> <p> <b>Documents:</b></p> <ul> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/BreakoutBoards/74HC595 Shift Reg Breakout-v11.pdf" target="_blank">Schematic</a></li> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/BreakoutBoards/74HC595 Shift Reg Breakout-v11.zip">Eagle Files</a></li> <li> <a href="http://dlnmh9ip6v2uc.cloudfront.net/datasheets/BreakoutBoards/MM74HC595.pdf" target="_blank">Datasheet</a> (MM74HC595M)</li> <li> <a href="http://bildr.org/2011/02/74hc595/" target="_blank">bildr blog - 74HC595 Project</a></li> </ul> Shift Register Breakout - 74HC595 http://www.sparkfun.com/products/10680 Shift Register Breakout Cascadeable 8 bit Serial In Parallel Out Shift Register 8 2V - 6V QA
