STMicroelectronics X-NUCLEO-ISO1A1 Isolated I/O Expansion board

STMicroelectronics X-NUCLEO-ISO1A1 Isolated I/O Expansion board is designed to expand the STM32 Nucleo board and provide micro-PLC functionality. This board with isolated industrial input/output allows rapid evaluation of the onboard ICs using the X-CUBE-ISO1 software package. The two X-NUCLEO-ISO1A1 boards can be stacked together on top of an STM32 nucleo board with the right selection of jumpers on the expansion board. This expansion board includes provision for Arduino connections. The X-NUCLEO-ISO1A1 board is RoHS compliant and is ideal for programmable logic controller applications.
