Preface

The SAME51J20A Curiosity Nano Evaluation Kit (EV76S68A) is a hardware platform used to evaluate the
®
SAME51J20A microcontroller (MCU), and it is supported by the MPLAB
X Integrated Development Environment
(IDE). The evaluation kit provides easy access to the features of the SAME51J20A to integrate the device into a
custom design. The Curiosity Nano series of evaluation kits includes an On-Board Nano Debugger, therefore no
external tools are necessary to program the SAME51J20A device. The SAME51J20A Curiosity Nano Evaluation Kit
is shown in the following figure.
