STMicroelectronics X-NUCLEO-OUT09A1/OUT19A1 Expansion Boards are based on IPS8160HQ/IPS8160HQ-1 octal high-side switches for STM32 Nucleo. These expansion boards provide a flexible environment for evaluating the IPS8160HQ/IPS8160HQ-1 switches in a digital output module connected to 0.7A and 1A industrial loads. The X-NUCLEO-OUT09A1/OUT19A1 operates with the microcontroller on the STM32 Nucleo via 3kV and 3.7kV optocouplers driven by GPIO pins and Arduino® R3 connectors. These expansion boards can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board. The X-NUCLEO-OUT09A1/OUT19A1 expansion boards feature a 10.5V to 36V operating range, 3kV galvanic isolation, undervoltage lock-out, and are RoHS compliant and CE certified.
