AT90USBKEY

The AT90USBKEY is an low cost demonstration board based on the Atmel AT90USB1287 microcontroller which allows quick evaluation of Atmel AVR microcontrollers and the AT90USB family. The key simply connects to the USB port of a personal computer to retrieve on board documentation and run AVR programs. Designers can either run demonstration programs or their own application. The board also permits access to the JTAG port and all the i/o's of the microcontroller for hardware development. An external power supply can be used for USB host or stand-alone operation. AT90USBKey dedicated to the AT90USB AVR microcontroller. This board is designed to allow an easy evaluation of the product using demonstration software. To increase its demonstrative capabilities, this stand alone board has numerous on board resources like USB, joystick, data-flash and temperature sensor. The AVRUSBKey is supported by AVR studio, version 4.12 or higher.
