AVR600: STK600 Expansion, routing and socket

boards

1 Introduction

This application note describes the process of developing new routing, socket and

expansion cards for the STK

creating such cards.

The STK600 starter kit from Atmel has a sandwich design to match a specific part

package and pin out to the generic pin headers. It also features an expansion area

where most part pins are available.

While the variety of IC packages is relatively limited, the number of possible pin

outs increases rapidly with the number of pins. i.e. a 6 pin IC can have 720 (6!)

different pin outs!

The routing / socket card design provides a low cost solution to support upcoming

devices as the socket is the cost driving factor.

STK600 users might also want to create their own routing cards to include

specialized hardware to prototype their design.
