+\section*{File Description}
+\textbf{File:} \texttt{30pin.h} \\
+\textbf{Description:} This header defines the 30pin recovery protocol structures, constants, and packet kinds.
+
+\section{Constants}
+\begin{itemize}[leftmargin=2em]
+    \item \texttt{CB\_30PIN\_MAG} - Magic number identifier for a 30pin packet. Defined as \texttt{"TP"}.
+    \item \texttt{CP\_30PIN\_MAG\_LEN} - Length of the magic number (\texttt{2} bytes).
+    \item \texttt{CB\_30PIN\_BUFFER\_LEN} - Length of the data buffer in the packet (\texttt{498} bytes).
+    \item \texttt{CB\_30PIN\_EOP\_LEN} - Length of the end-of-packet data (\texttt{11} bytes).
+\end{itemize}
+
+\section{Data Structures}
+\subsection{\texttt{cb\_tpin\_recovery\_packet}}
+\begin{lstlisting}[language=C]
+struct _cb_tpin_recovery_packet
+{
+    uint8_t mag[CP_30PIN_MAG_LEN];     // Magic number
+    uint8_t kind;                      // Packet kind identifier
+    uint8_t buffer[CB_30PIN_BUFFER_LEN]; // Packet data buffer
+    uint8_t eop[CB_30PIN_EOP_LEN];     // End-of-packet data
+};
+\end{lstlisting}
+
+\textbf{Typedef:} \texttt{cb\_tpin\_recovery\_packet\_t}
+
+\section{Enumerations}
+\subsection{Packet Kinds}
+Defines the kinds of packets used in the 30pin recovery protocol:
+
+\begin{itemize}[leftmargin=2em]
+    \item \texttt{TPIN\_RECOVERY\_PACKET\_KIND\_UNKNOWN = 0}
+    \item \texttt{TPIN\_RECOVERY\_PACKET\_KIND\_BOOT = 1}
+    \item \texttt{TPIN\_RECOVERY\_PACKET\_KIND\_DATA = 2}
+    \item \texttt{TPIN\_RECOVERY\_PACKET\_KIND\_EOP = 3}
+    \item \texttt{TPIN\_RECOVERY\_PACKET\_KIND\_EOP\_ACK = 4}
+    \item \texttt{TPIN\_RECOVERY\_PACKET\_KIND\_EOP\_NACK = 5}
+\end{itemize}
