Getting Started with X-NUCLEO-OUT01A1 industrial digital
output expansion board for STM32 Nucleo
Introduction
The X-NUCLEO-OUT01A1 industrial digital output expansion board for STM32 Nucleo is based on the
ISO8200BQ galvanic isolated octal high-side smart power solid state-relay.
It provides an affordable and easy-to-use development platform for implementing galvanic insulation in
industrial power switch driver applications.
The board can be plugged onto an STM32 Nucleo development board (NUCLEO-F103RB, NUCLEOF302R8 or NUCLEO-F401RE) via its Arduino® UNO R3 connectors.
Other boards can also be stacked to further expand functionality: industrial PLC functionality with 8
inputs and 16 outputs can be added with the X-NUCLEO-PLC01A1 expansion board, and the XNUCLEO-IDW01M1 expansion board adds wireless communication functionality for remote PLC
management, which is enhanced by the ST-PLC Android™ or iOS™ app.
This board is designed to comply with applicable industrial EMC standards.
