I/O Expanders
I/O Expanders, short for Input/Output Expanders, are integrated circuits (ICs) used to increase the number of input and output pins available to a microcontroller or other digital devices. They are particularly useful when you need to interface with a large number of sensors, switches, LEDs, or other peripherals but have limited available GPIO (General-Purpose Input/Output) pins on your microcontroller.
