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.

2 Routing cards

2.1 Connector footprints

The routing cards sit between the generic socket card and the STK600. It has one pair of electric pads underneath to mate with the STK600 spring loaded connector, and one pair of pads on top where the socket card connector connects. A part specific card with the target IC soldered on can be viewed as a routing card without the top pads.

A Routing card should have pads to mate with the following spring loaded connectors:

Figure 2-3. Clip hole dimensions

The board thickness should be 1.6mm to be compatible with the clips. Note that components on the main board might conflict with through hole mounted or

secondary side mounted components. Areas with such components are highlighted in the next figure
