STMicroelectronics X-NUCLEO-ISO1A1 Expansion Board Expansion Board X-NUCLEO-ISO1A1 [X-NUCLEO-ISO1A1]; 358-975
The STMicroelectronics evaluation board features isolated industrial input and output, designed to expand the STM32 Nucleo board and provide micro-PLC functionality. Two boards can be stacked on an STM32 Nucleo board with proper jumper selection to prevent GPIO conflicts. UL1577 certified digital isolators STISO620 and STISO621 ensure isolation between logic and process side components. Two current-limited high-side inputs from the process side are implemented using CLT03-2Q3.
