1 Introduction

The Atmel

AT32UC3C-EK is an evaluation kit and development system for the

Atmel AVR

UC3 AT32UC3C0512C microcontroller.

As a development system, the board notably provides on-board memory, a USB

communication interface, CAN and LIN network interfaces and the JTAG

programming and debugging interface. The AT32UC3C-EK also features

expansion headers; one of these is the wireless expansion header (named WLESS

header on the PCB).
