STEVAL-IFP047V1 [STMicroelectronics]

The STEVAL-IFP047V1 is an industrial digital output expansion board based on ISO808-1 and compatible with STM32 Nucleo.

It provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the ISO808-1 octal high-side smart power solid state relay, with embedded galvanic isolation, in a digital output module connected to 1.0 A industrial loads.

The STEVAL-IFP047V1 directly interfaces with the microcontroller on the STM32 Nucleo driven by GPIO pins and Arduino® R3 connectors, ensuring connectivity with either a NUCLEO-F401RE or a NUCLEO-G431RB development board.

The galvanic isolation between the microcontroller and the process stage is guaranteed by the ISO808-1.

It is also possible to evaluate a system composed of a STEVAL-IFP047V1 stacked on other expansion boards.
