Interface - I/O Expanders

I/O expanders operate as a slave device, responsible for sending data to and receiving data from microcontrollers through the MCU port. I/O expanders are used with microcontrollers, microprocessors, or similar devices to increase the number of signal connections that can be used to connect peripheral devices. This technique improves connectivity by increasing communication speed.
