# Board V1.0 with data sheet V1.3

## Question

Asked by juanito on 2014-01-02 in IO Modules.

Hi, I have a WIZ830MJ board, version 1.0. But now the data sheet is in its version 1.3 and the old one is not any more available. Is the 1.0 board fully compatible with the description given in this new datasheet?? is there any physical change in the connections at J1 and J2?

Thanks.
