The hardware development kit consists of an industrial sensor board (STEVAL- IDP005V1), an adapter for the ST-LINK/V2-1 programming and debugging tool DB3663 - Rev 2 - January 2019 www.st.com For further information contact your local STMicroelectronics sales office.STEVAL-BFA001V1B (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.
