STMicroelectronics STEVAL-IFS017V1

Overview

STEVAL-IFS017V1 from STMicroelectronics is a USB-powered demonstration board based on the STM32 microcontroller, serving as a motherboard for evaluating multiple temperature sensors (e.g., STLM20, STTS75, STLM75) and RTCs (e.g., M41T82SM6, M41T83SQA6). It enables register-level access and feature demonstration via a graphical user interface.

For engineers reviewing the STEVAL-IFS017V1 datasheet, STEVAL-IFS017V1 pinout, STEVAL-IFS017V1 application, or STEVAL-IFS017V1 equivalent, this board supports rapid validation of ST's analog sensor and real-time clock ICs in lab-based thermal monitoring and timekeeping system development.

Technical Context

The board implements a modular evaluation architecture: the STM32 host MCU communicates with interchangeable daughter cards over I²C, supporting up to eight temperature sensors and three RTCs simultaneously. Firmware provides register read/write capability and real-time data visualization.

It operates exclusively from USB 5 V power with no external supply required, and includes dedicated signal conditioning, level-shifting, and connector interfaces (e.g., 2×10-pin headers) for daughter card attachment and GUI communication.

FAQ

Does STEVAL-IFS017V1 require external power or programming hardware?

No. The board is fully USB-powered and preloaded with firmware. No external power supply, JTAG debugger, or programming tool is needed - connection to a Windows PC via USB initiates immediate GUI operation and device enumeration.

Which daughter cards are compatible with STEVAL-IFS017V1?

Only ST-branded daughter cards matching the documented mechanical and electrical interface - including ST's official temperature sensor cards (e.g., STEVAL-IFP017V1 for STLM75) and RTC cards (e.g., STEVAL-IFR017V1 for M41T83SQA6) - are supported per the schematic and layout constraints.

Can STEVAL-IFS017V1 evaluate non-ST temperature sensors or RTCs?

No. The firmware, I²C address mapping, register definitions, and GUI parsing logic are hardcoded for the specific ST devices listed in the data brief (STLM20, STTS75, M41T82SM6, etc.). Non-ST parts will not be recognized or configured correctly.

Is source code or firmware update capability provided for STEVAL-IFS017V1?

No. ST did not release the STM32 firmware source code or bootloader interface for this board. The GUI application communicates with closed-binary firmware; no field upgrade path or customization options are documented or supported.
