6.3 Cellular Arduino Shield Arduino-Compatible Expansion Headers
The Cellular Arduino Shield includes Arduino-compatible headers that enable interfacing with S5D9 MCU board. Most
of the interface signals are connected directly to the BG96 module pins. This enables direct control of BG96 module
depending on the application needs.
The table below shows the mapping between the Arduino headers pins and the BG96 module pins connected to them
along with their primary functions.
