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.

Here you place the AVR. See Placing the AVR for more details.
This is the connection that lets you upload and debug your application
with the JTAGICE mk II. See JTAG programming and JTAG debugging.
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.
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.
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.
