STMicroelectronics X-NUCLEO-OUT14A1 Expansion Board

STMicroelectronics X-NUCLEO-OUT14A1 Expansion Board is an industrial digital output expansion board based on the ISO808A-1 for STM32 Nucleo. The board offers a powerful and flexible environment to evaluate the ISO808A-1 octal high-side smart power solid-state relay. The ISO808A-1 features embedded galvanic isolation and a 20MHz SPI control interface in a digital output module connected to 1A industrial loads.

The STMicro X-NUCLEO-OUT14A1 expansion board directly connects with the microcontroller on the STM32 Nucleo driven by GPIO pins and Arduino® R3 connectors. The ISO808A-1 ensures galvanic isolation between the microcontroller and the process stage.

The expansion board can be interfaced with either a NUCLEO-F401RE or a NUCLEOG431RB development board. It is also achievable to evaluate a 16-channel digital output system allowing the daisy-chaining feature on two X-NUCLEO-OUT14A1 stacked expansion boards.
