STMicroelectronics X-NUCLEO-OUT07A1 Digital Output Expansion Board is based on IPS4260LM quad low-side switch for STM32 Nucleo. This expansion board provides a robust and adaptable environment for the evaluation of the driving and diagnostic capabilities of the IPS4260LM smart power solid-state relay. This is useful in digital output modules connected to 0.5A industrial loads. The system allows user configuration as a dual digital output module for 1A industrial loads or a single digital output module for 2A industrial loads. The X-NUCLEO-OUT07A1 board interfaces with the microcontroller on the STM32Nucleo via STISO620 and STISO621 digital isolators and Arduino® R3 connectors. This expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board. The X-NUCLEO-OUT07A1 board is designed to meet the application requirements for the galvanic isolation between the user and power interfaces.
