allows you to interact with all your printers via the Cloud, and many other exciting new features.
When I ordered from jj, they did not have a US distributor or if they did, it wasn't very well advertised.
The EEB is a single board system and runs a better firmware that what was available on the jj board. It is essentially the same thing. You can use it for all the same projects.
EEB is $50 for everything you need. With jj, the total cost for all parts is $48.73 and that is with a couple dollars off the Leonardo board. So without the sale price, jj is more expensive.
EDIT: The $48.73 price was for individual parts. I see they have a kit available for $48.02.
