Overview
This document describes the STK525 dedicated to the AT90USBxxx AVR
microcontroller. This board is designed to allow an easy evaluation of the product using
demonstration software.
To complement the evaluation and enable additional development capability, the
STK525 can be plugged into the Atmel STK500 Starter Kit Board in order to use the
AT90USBxxx with advanced features such as variable VCC, variable VRef, variable
XTAL, etc. and supports all AVR development tools.
To increase its demonstrative capabilities, this stand alone board has numerous on-
board resources (USB, RS232, joystick, data-flash, microphone and temperature
sensor).
This user guide acts as a general getting started guide as well as a complete technical
