CPU cards, computer on modules or complete computers often have a variety of I/O capabilities as a standard. In fact, if you want to control specific things you cannot avoid adding extra I/O. Indeed, that is why I/O is sometimes referred to as the “hands and feet” of a computer system.
We have a number of manufacturers in our range with many different standard I/O plug-in cards. Increasingly, you also see freely programmable FPGA on plug-in cards in order to provide the customer with flexibility.
