ATmega88 "Quick Start" Kit
If you're just starting out with Atmel AVR microcontrollers or have recently purchased the AVR Dragon, you may not be looking for a complete solution to working with multiple devices using multiple programming and on-chip debug interfaces. If you just want to get a feel for the AVR Dragon using a single AVR device, then the "Quick Start" Kit may be for you.
The Quick Start Kit contains everything you need to turn your AVR Dragon and Dragon Rider 500 PCB into a development, evaluation and experimentation platform for the Atmel ATmega88 microcontroller. It supports programming via ISP (in-system programming) and on-chip debugging via debugWIRE. The LED and Switch Add-on Parts Kit is included, plus the microcontroller itself.
Price and Ordering
Due to low demand, the Dragon Rider 500 Quick Start Parts Kit is no longer offered for sale. This page is maintained for people who have previously purchased this kit. An equivalent entry-level Dragon Rider 500 consists of the Dragon Rider PCB with Basic Parts Kit, the LED and Switch Add-On Parts kit and an ATmega88 or ATmega168 microcontroller. These can all be purchased from the Dragon Rider 500 introduction page.

For assembly suggestions, refer to the Parts & Assembly page and the User's Guide. Solder the LED and switch circuits onto the board along with the other parts, rather than leaving them until last (although it really doesn't matter much). Resistors will be first, then the push-button switches, then transistors and LEDs and finally the headers. Consider not pushing the LEDs right down to the board. If you let them stand up a little on their leads, slightly above the tops of the transistors, they will be easier to see. Note that the reset switch (SW0) has a very short actuator (to reduce the chances of it getting pressed by accident) but the switches in the add-on kit (SW3 to SW7) have longer actuators for easier use. Don't get them mixed up!
The single-row, 24-pin header strip should be snapped into seven three-pin sections for J11, J12, J13, J16, J22, J23 and J24 and three single pins for J22, J23 and J24.
