The Atmel Dragon is an inexpensive tool which connects to a PC via USB. The Dragon can program all AVRs via JTAG, HVP, PDI,<ref>{{cite web|url=http://www.atmel.com/dyn/resources/prod_documents/doc8169.pdf |archive-url=https://web.archive.org/web/20091007220729/http://www.atmel.com/dyn/resources/prod_documents/doc8169.pdf |archive-date=2009-10-07 |url-status=live|title=AVR1005: Getting started with XMEGA, page 7|publisher=Atmel|access-date=7 November 2011}}</ref> or ICSP. The Dragon also allows debugging of all AVRs via JTAG, PDI, or debugWire; a previous limitation to devices with 32&nbsp;KB or less program memory has been removed in AVR Studio 4.18.<ref>{{cite web|url=http://www.atmel.com/dyn/resources/prod_documents/releasenotes_avrstudio418.txt|title=AVR Studio v4.18 Release Notes|access-date=2012-09-19}}</ref> The Dragon has a small prototype area which can accommodate an 8, 28, or 40-pin AVR, including connections to power and programming pins. There is no area for any additional circuitry, although this can be provided by a third-party product called the "Dragon Rider".<ref>{{cite web|url=http://www.ecrostech.com/AtmelAvr/DragonRider/|title=ECROS Technology - Dragon Rider|date=2008-03-02|publisher=Ecrostech.com|access-date=2012-09-19}}</ref>
