Preface

The Atmel

®

 ATtiny104 Xplained Nano evaluation kit is a hardware platform to

evaluate the ATtiny104 microcontroller.

Supported by the Atmel Studio integrated development platform, the kit
provides easy access to the features of the Atmel ATtiny104 and explains
how to integrate the device in a custom design.

The Xplained Nano MCU series evaluation kits include an on-board mini
embedded programmer, and no external tools are necessary to program the
ATtiny104.
