STEVAL-FSM01M1 Advanced dual channel digital I/O module for safe automation

STEVAL-FSM01M1 is a safe dual channel digital I/O expansion board compatible with the STM32 Nucleo. Its system architecture reflects our long-term experience with designing digital I/O applications to reach the highest-grade robustness and to meet the requirements on reliability of operation in the most challenging industrial environments such as factory automation and functional safety.

While the majority of standard Nucleo expansion shields are usually plugged-in on top of an STM32 Nucleo board using the ARDUINO® Uno V3 connectors, the STEVAL-FSM01M1, in contrary, provides the base for the Nucleo that is connected on top of it by means of its onboard ST morpho extension headers.

The microcontroller pins and peripherals handling the operation of the STEVAL-FSM01M1 are physically separated from those used by other X-NUCLEO boards eventually connected to the system.

Additional expansion shields can be easily added on top of the stack to extend system functionality without introducing any overlap of the used microcontroller resources.

The associated STM32 firmware package STSW-FSM01 is compatible with NUCLEO-F401RE and it can be easily adapted to run on any other STM32 Nucleo platform.
