The DS1921K Thermochron™ iButton® Starter Kit provides the basic hardware for a quick evaluation of Maxim’s Thermochron iButton family that communicates using the 1-Wire® protocol. The kit uses the USB port of a Microsoft Windows®-based Personal Computer running Vista®, XP SP2 (or higher), or Microsoft Server Operating Systems Windows 2003 or 2008. The kit includes a DS1921 Thermochron iButton and all hardware required to communicate with it. The DS1921K is also capable of evaluating any other iButton, including the high-capacity Thermochrons (DS1922L, DS1922T, and DS1923), the Hygrochron (DS1923), and the temperature-only iButton (DS1920). Please note that the DS1921 is the only iButton included in the kit. All other iButtons may be purchased separately. The easy setup process includes the free download of 1-Wire drivers and the OneWireViewer demonstration software to easily communicate with iButtons through the PC's USB port. The download site for the free 1-Wire drivers and bundled OneWireViewer is found at:
For software developers who wish to create custom iButton applications, Maxim provides documentation and a free library of source code examples at http://www.maxim-ic.com/ibutton under the Software Development Kits link. Please check our website regularly for software updates.
To evaluate plastic-packaged 1-Wire devices instead of the iButton form factor, use the DS9090K instead of the DS1921K. To evaluate any iButtons other than Thermochrons, see the DS9092K.
