IOX

IOX is an acronym that is used in multiple technology-related contexts to denote concepts related to input/output (I/O). There is no single standardized definition for IOX, and its meaning varies with the domain, vendor, or project. In hardware and embedded systems, IOX commonly refers to I/O expansion modules or I/O extension interfaces that increase the number or capability of I/O pins available to a microcontroller or single-board computer. These modules are typically connected via serial or parallel interfaces such as I2C, SPI, or PCIe and are used to monitor sensors or control actuators in compact or space-constrained environments.

In software, IOX can denote inputs/outputs extension libraries, runtime environments, or middleware that manage data streams or asynchronous I/O operations. Such software components are used to improve throughput, reduce latency, and decouple application logic from device I/O.

In industrial automation and Internet of Things contexts, IOX branding appears on platforms and devices designed to standardize sensor and actuator connectivity, data acquisition, and device management. These platforms may provide configuration tools, drivers, and protocol adapters to integrate diverse equipment.

Because IOX is not a universally defined term, users should consult the specific product documentation to understand what IOX denotes in that context. See also I/O, I/O expansion, data interface, and industrial automation platforms.
