AVR Dragon can be used with an external target board. However, the onboard prototype
area, allow simple programming and debugging without any additional hardware. 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) 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: It the target board is powered by external power source, no connection should be
made betwwen the VCC connector and the external board.
AVR Dragon if fully supported by AVR Studio. This allows the AVR Dragon firmware to be
easily updated to support new devices and protocols. When connecting the AVR Dragon,
AVR Studio will automatically check the firmware and prompt the user if an updated
firmware is available.
