How to linebreak when using \rotatebox inside a tikz node?

Question

I would like to know how I can get a linebreak inside a rotated node using tikz. I tried to use the align=center option together with \rotatebox{}{}, but i get an error. Here is an example of a working code but without the linebreak:

\begin{figure}[h!tp]
\begin{tikzpicture}[generaloptions/.style 2 args={
draw,ultra thick,font={\bfseries},inner sep=0,outer sep=0,minimum height=#1,minimum width=#2}]
\node[generaloptions={3.5cm}{1.5cm},align=center,anchor=south west,font=\footnotesize\bfseries] (l1) at ([xshift=-1.5cm]big.south west) {\rotatebox{90}{Line Break}};
\end{tikzpicture}
\end{figure} 

I would like something like this but instead i get an error:

\begin{figure}[h!tp]
\begin{tikzpicture}[generaloptions/.style 2 args={
 draw,ultra thick,font={\bfseries},inner sep=0,outer sep=0,minimum height=#1,minimum width=#2}]
 \node[generaloptions={3.5cm}{1.5cm},align=center,anchor=south west,font=\footnotesize\bfseries] (l1) at ([xshift=-1.5cm]big.south west) {\rotatebox{90}{Line \\ Break}};
 \end{tikzpicture}
 \end{figure}

I am I missing something? Thanks!

rotatebox tries to rotate every thing inside as if it were a box. Hence you can't expect a line break. You may put the content inside a parbox

\documentclass{article}

\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[generaloptions/.style 2 args={
 draw,ultra thick,font={\bfseries},inner sep=0,outer sep=0,minimum height=#1,minimum width=#2}]
 \node[generaloptions={3.5cm}{1.5cm},align=center,anchor=south west,font=\footnotesize\bfseries] (l1) at (0,0) {\rotatebox{90}{\parbox[c]{1.5cm}{\centering Line  Break}}};
 \end{tikzpicture}
\end{document}

If you want to rotate the text alone and have line break, you may use the option rotate=90,text width = 1.5cm (and ditch the rotatebox):

\documentclass{article}

\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[generaloptions/.style 2 args={
 draw,ultra thick,font={\bfseries},inner sep=0,outer sep=0,minimum height=#1,minimum width=#2}]
 \node[generaloptions={1.5cm}{3.5cm},text width = 1.5cm,align=center,anchor=south west,font=\footnotesize\bfseries,rotate=90] (l1) at (0,0) {Line  Break and break yes };
 \end{tikzpicture}
\end{document}

You may have to interchange the minimum height and minimum width though.
