The Dragon Rider 500 is a development system produced by Ecros Technology. It provides a means of interfacing 8, 20, 28, and 40 pin microcontrollers with the Dragon's programming functions and includes development opportunities such as RS232, LED, Button, and LCD prototyping through its add-on packages. This creates a marriage of the functionality of the STK500 with features of the AVR Dragon.
My fiancee gave me this kit as a birthday present and I think it's a great gift! Stay away fellas, she's spoken for.
Update: I had sent several inquires to Graham Davies of Ecros Technology while I was working on this project. He was extremely helpful and once he saw this instructable, offered to send me a complimentary LCD and Ribbon Cable Add-on Kit as these were the only two that I didn't have. Those kits are detailed in steps 14 and 15. Thank you Ecros Technology!
It should be noted that during this instructable components of all Add-on kits will be installed concurrently. These packages are not necessarily designed to be installed one at a time.
