With the
AVR Dragon, Atmel has set a new standard for low cost development tools. AVR Dragon supports all programming modes for
the Atmel AVR device family. It also include full emulation support for devices with 32kB or less Flash memory.
At a fraction of the price traditionally associated with this kind of featured tool, the AVR Dragon will fulfill all your programming and
At a fraction of the price traditionally associated with this kind of featured tool, the AVR Dragon will fulfill all your programming and
emulation needs. The flexible and secure firmware upgrade feature allows AVR Studio to easily upgrade the AVR Dragon to support new
devices.

AVR Dragon can be used with an external target board. However, the onboard prototype area, allow simple programming and debugging
without any additional hardware besides strapping cables. Please see the
Using the AVR Prototype Area
section for a description on how
to use this.
AVR Dragon is powered by the USB cable, and can also source an external target with up to 300mA (from the VCC connector, 5V) when
AVR Dragon is powered by the USB cable, and can also source an external target with up to 300mA (from the VCC connector, 5V) when
programming or debugging. For more information on technical details, please read the
AVR Dragon Requirements
section. If the target is
already powered by an external power source, the AVR Dragon will adapt and level convert all signals between the target and the AVR
Dragon.
Note: If the target board is powered by external power source, no connection should be made betwwen the VCC connector and the

protocols. When connecting the AVR Dragon, AVR Studio will automatically check the firmware and prompt the user if an updated
firmware is available.
