The STMicroelectronics industrial digital output expansion board for STM32 Nucleo. It provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS1025HF single high-side, smart power, solid-state relay in a digital output module connected to 2.5 A industrial loads. The X-NUCLEO-OUT15A1 interfaces with the microcontroller on the STM32 Nucleo via 5 kV optocouplers driven by the GPIO pins and Arduino® UNO R3 connectors. The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board.
