It is a board to plug in module boards that have a I2C interface. Many devices such as sensors like temperature, humidity, pressure, acceleration, etc, have I2C interfaces to make it easy to connect multiple devices to a singe serial interface. Companies such as Adafruit and Sparkfun sell breakout boards for devices that use I2C interfaces and while they are not designed to work with the POT board, they can give you an idea of the uses for them.
