# WIZ550WEB version 1.1 - any datasheet for it?

## Question

Asked by flotul on 2018-01-13 in General.

Hi,

I received my WIZNet550WEB evaluation board a few days ago and was surpised to discover a version 1.1 (I assume it is brand new ![:grinning:](https://emoji.discourse-cdn.com/twitter/grinning.png?v=12)).

Is there any datasheet update for this version?

Mainly, what are the buttons’s functions?

Thanks

Roger

Hi flotul.

Did you boot WIZ550web from boot mode?

Did you used UART0?

Thank you.
