The NORVI X-UARTIO is a versatile communication expansion module for the NORVI X modular controller platform.
It provides multiple serial communication interfaces including RS485, RS232, and UART, enabling flexible connectivity to industrial devices, sensors, meters, and peripherals. The module uses shared MCU I/O lines with intelligent switching, allowing multiple physical ports to be supported while minimizing processor pin usage. Interface selection is fully controlled via firmware.
