Geckodrive G251 (2 off)

Had these lying around gathering dust for some time now, and currently have no plans for them. They're still in the original packaging they came in, and have only ever been taken out to admire just how small they are.

Details from Geckodrives website are-

The G251 is one of Geckodrive's newest low-price, high-quality step motor drives. The G250 is produced using brand new techniques allowing it to be sold for very low prices in volume while maintaining excellent quality. This is in essence a miniaturized version of the G201 complete with a heatsink plate and 3.5mm 12 position connector.
