STMicroelectronics STEVAL-FSM01M1 Digital I/O Expansion Board

STMicroelectronics STEVAL-FSM01M1 Digital I/O Expansion Board is a safe dual-channel digital I/O expansion board compatible with the STM32 Nucleo. The board features system architecture, providing STMicro’s long-term experience with designing digital I/O applications to reach the highest-grade robustness and meet the requirements for reliability of operation in the most challenging industrial environments, such as factory automation and functional safety.

Most standard Nucleo expansion shields are usually plugged in on top of an STM32 Nucleo board using the ARDUINO® Uno V3 connectors. The STMicro STEVAL-FSM01M1 Digital I/O Expansion Board offers the base for the Nucleo that is connected on top of it, employing its onboard ST morpho extension headers. The microcontroller pins and peripherals handling the operation of the STEVAL-FSM01M1 are physically separated from those operated by other X-NUCLEO boards eventually connected to the system.

Additional expansion shields can be easily added to the stack to extend system functionality without presenting any overlap of the used microcontroller resources. The STM32 firmware package STSW-FSM01 is compatible with NUCLEO-F401RE and can be easily adapted to run on any other STM32 Nucleo platform.
