Great job, LOIC, I do have two remarks :
First of all, on the site you may select compare but I did not found the link www.industruino.com/catalog/product_compare
For the case, I like to see that the connectors have a break-out cover so that if you don't need the I/O on the bottom you don't see them.
This is really an advantage whenever you have to place the unit elsewhere and not in a cabinet on rail.
Regards, Robert.
