The STEVAL-IFS017V1 demonstration board provides an evaluation platform for testing multiple temperature sensor and real-time clock (RTC) ICs from STMicroelectronics. The STEVAL-IFS017V1 acts as a motherboard based on the STM32 microcontroller, to which different daughter cards with temperature sensors and RTCs can be connected. The temperature sensors supported by this system are: the STLM20, STTS424E02, STTS75, STDS75, STLM75, STCN75, STTS751, and STTS2002. RTCs supported by this system are: the M41T82SM6, M41T83SQA6, M41T83SMY6. The STEVAL-IFS017V1 demonstration board can operate in USB powered mode with a graphical user interface (GUI). The graphical user interface is used to access the registers and demonstrate the features of temperature sensors and RTCs.
