Description
The STEVAL-BFA001V1B is an industrial reference design kit designed for condition
monitoring (CM) and predictive maintenance (PdM).
The hardware development kit consists of an industrial sensor board (STEVAL-
IDP005V1), an adapter for the ST-LINK/V2-1 programming and debugging tool

(STEVAL-UKI001V1), a 0.050” 10-pin flat cable, a 4-pole cable mount connector plug
with male contacts and an M12 female connector with a 2 m cable.
The firmware package includes dedicated algorithms for advanced time and
frequency domain signal processing and analysis of the 3D digital accelerometer with
3 kHz flat bandwidth. The package includes drivers for pressure, relative humidity
and temperature sensor monitoring. Audio algorithms for acoustic emission (AE) are
also part of the package.
The firmware runs on the high performance STM32F469AI, ARM
®
Cortex
®
-M4, 32-
bit microcontroller and the sensor data analysis results are sent via wired connectivity
based on IO-Link device transceiver (IO-Link stack protocol not included).
The STEVAL-BFA001V1B reference design is suitable for monitoring motors, pumps
and fans, and can accelerate the development of predictive maintenance solutions.
The package also allows connection with the STEVAL-IDP004V1 IO-Link master
capable, multi-port evaluation board; a PC GUI included in the package displays the
algorithms output and sensor data. The data can also be displayed on a PC using a
common terminal emulator by simply connecting the STEVAL-IDP005V1 to a PC
through the STEVAL-UKI001V1 adapter and ST-LINK/V2-1 included on any STM32
Nucleo-64 development board.
The package includes an industrial M12 cable for power or connection with a master
port. The connection is managed using a standard multipolar cable with one wire
used for IO-Link data, one for the L+ line (positive supply voltage pole) and one for
the L- line (negative supply voltage pole).
The layout is designed to meet IEC61000-4-2/4 and EN60947 requirements for
industrial applications.
The STEVAL-IDP005V1 is specifically designed with dimensions (50mm x 9mm x
9mm) that reflect real industrial applications and needs.
The firmware is freely available on
STSW-BFA001V1.
