In the case multiple nodes of the same kind are connected to the I2C "daisy-chain", they may have the same I2C default address, causing communication problems. All Modulino® nodes are designed to have the possibility of having different I2C addresses via hardware or firmware changes as presented in the following table.
| MODULINO BUTTONS | Three SPST Push Buttons | 0x7C | Any custom address (via software configuration)| 0x3E |

**Please note:** When scanning for I2C addresses connected to the bus, the boards might identify themselves using the **Hardware I2C Address** listed in the last column of the table. However, you should always use the **Modulino I2C Address** provided in your code if using the official Modulino library.

With the provided software, users can change the default I2C address of the dedicated I2C interface controller firmware. Assigning different addresses allows users to connect multiple boards of the same type in a chain.

To facilitate this, a white rectangle is positioned on the bottom silk of the board, where users can write the new I2C address directly on the board itself.
