STMicroelectronics X-NUCLEO-OUT06A1 Expansion Board is used for the evaluation of the driving and diagnostic capabilities of the IPS1025H-32. The IPS1025H-32 is a single high-side smart power solid state relay, in a digital output module connected to 5.7 A industrial loads. The X-NUCLEO-OUT06A1 interfaces with the microcontroller on the STM32 Nucleo via 5kV optocouplers driven by GPIO pins and Arduino UNO R3 connectors. The expansion board can be connected to either a NUCLEO-F401RE or NUCLEO-G431RB development board.
