They also have other versions with more of all the above, plus two with ADC on board, one five channel 8bit, one 5 channel 16 bit. They also have a IIC demo board which has all sorts of peripheral chips on it ... for about NZ$190. PS I have no connection with Philips - I just think these are a rather nice range of devices.
