Yep, yep, I got one and I am about to test it out. Will post results as soon as I am done. It will work for drives that operate off of 5V power (laptop HDD and CD drives). Will not operate 12V devices though. There is a 12V pass through on the board. Also, the board does not need external voltage regulation. Regulation is built into the board and will work down to 8V. This is perfect for me cause I am designing my own Startup/Shutdown controller. I got mine from an Ebay auction that the company had. Paid a lot less than what the website price was. Also, last time I checked the site was out of the retail versions.
