There are several devices that make up the controller system. Here are the i2c device addresses, of which most can easily be changed in the software configuration.  Note that the mcp23017, address 25 is for future expansion.  Also, the pca9635 will use 3 addresses, but the only one that needs to be configured is 0X1f, the other two are defaults.

Secondarily, this table below shows the default device pins that the various sensors, buttons, and other devices are connected to.  These can also be easily changed in the environment file (see software page).
