+\begin{itemize*}
+    \item\question{One (final) converter board serves one ladder (whatever that means, e.g. 5)
+sensors and has its own JTAG chain} This removes both queue and termination boards.
+    \item Design of the converter board should be in a way to easily change the number of sensors,
+i.e. all electronics should be modular, eithre independent for each sensor - or shared between all
+of them.
+    \item For the telescope, the board should support two sensors.
+\end{itemize*}
 
+\subsection{Components}
+\begin{itemize*}
