STMicroelectronics X-NUCLEO-DOL10A1 Expansion Board
STMicroelectronics X-NUCLEO-DOL10A1 Expansion Board is an industrial digital output expansion board for STM32 Nucleo. It provides a powerful and flexible environment for evaluating the driving and diagnostic capabilities of the IPS1050LQ single low-side smart power solid-state relay, featuring configurable smart overload protection. The X-NUCLEO-DOL10A1 expansion board interfaces with the microcontroller on the STM32 Nucleo via STISO620 and Arduino® UNO R3 connectors. The expansion board can be connected to either a NUCLEO-G431RB or a NUCLEO-F401RE development board.
The STMicroelectronics digital isolators STISO620 (featuring 2.8kVRMS galvanic isolation) and the isolated DC-DC DC1 (featuring 3kVDC isolation) protect the logic side from the typical harsh environment on the process side. 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, depending on the setting of SW7). The onboard Arduino UNO R3 connectors enable the connection to either a NUCLEO-G431RB or a NUCLEO-F401RE development board.
