I/O expanders are integrated circuits used to increase the number of input/output (I/O) pins available in microcontroller-based systems. They provide additional I/O ports through serial communication interfaces such as I2C or SPI. I/O expanders are used in applications requiring more I/O capability than provided by the microcontroller, including home automation, industrial control, and consumer electronics. Their ability to expand I/O capacity efficiently makes them valuable for enhancing the functionality of embedded systems.
