AT90USBKEY2 (652528) KIT DEMO FOR AT90USB

The low-cost demonstration board based on the Atmel AT90USB1287 microcontroller 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 IOs of the microcontroller for hardware development. An external power supply can be used for USB host or stand-alone operation.
