STMicroelectronics X-NUCLEO-DO4xA1 Digital Output Expansion Boards
STMicroelectronics X-NUCLEO-DO4xA1 Digital Output Expansion Boards are designed for the STM32 Nucleo. The STMicroelectronics X-NUCLEO-DO4xA1 expansion boards provide a powerful, flexible environment for evaluating the driving/diagnostic capabilities of the IPS4140HQ quad high-side smart power solid-state relay in a digital output module connected to ≤0.6A industrial loads. The X-NUCLEO-DO4xA1 expansion boards offer two application sides (a logic side and a process side) electrically separated by the 2.8kVRMS galvanic isolation featured by the STISO621 digital isolators. The logic side is the application side where the MCU operates, and it is supplied by the VISO_L rail (3.3V or 5.0V, according to the setting of SW1). The onboard Arduino UNO R3 connectors enable the connection to either a NUCLEO-F401RE or a NUCLEO-G431RB development board. The boards can also evaluate a system consisting of an X-NUCLEO-DO40A1 expansion board stacked on other expansion boards compatible with logic signal assignments.
