ATtiny3217 Xplained Pro

Preface

The ATtiny3217 Xplained Pro evaluation kit is a hardware platform to evaluate the ATtiny3217 microcontroller.

Supported by the Atmel Studio and MPLAB

X integrated development platform, the kit provides easy access to the

features of the ATtiny3217 and explains how to integrate the device into a custom design.

The Xplained Pro MCU series evaluation kits include on-board Embedded Debuggers. No external tools are
necessary to program or debug the ATtiny3217.

Xplained Pro extension kits offer additional peripherals to extend the features of the board and ease the development
of custom designs.
