STMicroelectronics STEVAL-IFP042V1 Digital Output Expansion Board

STMicroelectronics STEVAL-IFP042V1 Industrial Digital Output Expansion Board is based on the ISO808A and is compatible with STM32 Nucleo. It provides a powerful and flexible environment for evaluating the driving and diagnostic capabilities of the ISO808A octal high-side smart power solid state relay, with embedded galvanic isolation and 20MHz SPI control interface, in a digital output module connected to 0.7A industrial loads.

The STMicroelectronics STEVAL-IFP042V1 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 ISO808A guarantees the galvanic isolation between the microcontroller and the process stage. Evaluating a 16-channel digital output system with a STEVAL-IFP042V1 stacked on other expansion boards is also possible.
