Global I-O Expander Market Research Report, Competitive, Technology and Forecast Analysis 2025-2032

Research Summary

An I/O (Input/Output) expander is a hardware component or integrated circuit (IC) that increases the number of input and output pins available for a microcontroller or microprocessor. It is used in applications where additional I/O capabilities are needed without upgrading to a larger microcontroller. I/O expanders communicate with the main processor via protocols like I²C, SPI, or GPIO, allowing multiple digital or analog devices to be controlled or monitored using fewer pins on the host controller. These devices are widely used in embedded systems, robotics, and consumer electronics to interface with sensors, switches, LEDs, displays, and other peripherals. By simplifying circuit design and conserving valuable processor resources, I/O expanders enhance the functionality and scalability of electronic systems.
