Preface
The ATtiny3217 Xplained Pro evaluation kit is a hardware platform to evaluate the ATtiny3217
microcontroller.
Supported by the Atmel Studio 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.
