 ### Expansion Port
 The expansion port can be used to daisy-chain several Opta® Expansions and additional modules. To be accessed needs to be freed up from its breakable plastic cover and the connection plug added between each device.
 
+It supports up to 5 expansion modules. To avoid potential communication issues, ensure the total number of connected modules does not exceed 5.
+
+If any issues occur with module detection or data exchange, double-check the connections and ensure the **Aux connector and clips are securely installed** within the expansion port. If problems persist, inspect for any loose or improperly connected cables.

 ## Device Operation
 ### Getting Started - IDE
 If you want to program your Arduino Opta® Digital Expansions while offline you need to install the Arduino® Desktop IDE **[1]** and the Arduino_Opta_Blueprint using the Library Manager. To connect the Arduino Opta® to your computer, you will need a USB-C® cable.
