STEVAL-IFS003V1
Temperature sensor board based on
STLM75/STDS75 and ST72F651AR6
Features
■ ST72F651 microcontroller used for
temperature monitoring, data logging and fan
speed regulation
■ USB-powered board capable of working in
stand-alone mode using the GUI
Description
The purpose of this product evaluation board is to
demonstrate the features of temperature sensors
STDS75 and STLM75. The board consists of the
ST72F651AR6 microcontroller, the STLM75 and
STDS75 temperature sensors, and a NAND flash.
The board functions in two operating modes:
stand-alone / external power mode and USB-
powered mode. When this product evaluation
board is connected to a computer through a USB
cable, it will also function as a mass storage
device. The default state of the board is “mass
storage mode”, and can be switched to
“temperature sensor mode” using the GUI
(graphical user interface).
