Getting Started

In this chapter you will get an overview of all the features of the STK503. You will

learn how to use the STK503 with STK500 and how to mount the AVR in the ZIF

socket.

Hardware overview

The STK503 is a flexible tool to start developing and debugging applications for

100-pin AVRs as the ATmega2560. There are connectors for all available

signals, making it easy to connect to your own hardware, if required.

Figure 3-1: STK503

ZIF socket:

Here you place the AVR. See Placing the AVR for more details.

JTAG connector:

This is the connection that lets you upload and debug your application

with the JTAGICE mk II. See JTAG programming and JTAG debugging.

ISP connector:

By mounting a cable between this connector and the programming

connector on STK500, you can easily upload new programs to the AVR.

See In-System Programming for a description on how to use AVR Studio

and how connect the cable.

Clock source switches:

The STK503 has two switches that lets you select between different on-

board and external clock sources. This is described in the Clock options

chapter.

SRAM footprint:

The board has a footprint for an SRAM chip. No SRAM is mounted, so

you can select an SRAM with the right operating voltage. For more

information on using the SRAM and it connection, see the External

Memory Interface chapter.
