Cheap arduino alternative based on the Cortex M0

This is for all the tinkers out there that also enjoy electronics. I found this gem on ebay for $2.00 each with free delivery!

When it came, it is actually from the manufacture and all the support can be found here;
The site says that they are selling them for $19.95

Anyway, just received them and starting to play with it. Great if you like this stuff!
