Oh ! Then I guess Goggle search must have left this out. Check the following URLs for more information.

It's a assembled ethernet controller (Realtek RTL8019AS) on a small form factor to enable you to prototype ethernet stuff at US$30.

Check the main site for other variants of ethernet controller (Cirrus CS8900A as well as ASIX AX88796L).

Hope that helps.
