Preface

The SAM D21 Curiosity Nano Evaluation Kit (DM320119) is a hardware platform to evaluate the SAMD21G17D
microcontroller (MCU), and it is supported by the MPLAB

®

 X Integrated Development Environment (IDE). The

evaluation kit provides an easy access to the features of the SAMD21G17D to integrate the device into a custom
design. The Curiosity Nano series of evaluation kits include an On-Board Nano Debugger, hence external tools are
not required to program the SAMD21G17D device. The SAM D21 Curiosity Nano Evaluation Kit is shown below.
