ATtiny1607 Curiosity Nano
ATtiny1607 Curiosity Nano Hardware User Guide
Preface
The ATtiny1607 Curiosity Nano evaluation kit is a hardware platform to evaluate the ATtiny1607
microcontroller.
Supported by Atmel Studio/Microchip MPLAB
®
X Integrated Development Environment (IDE), the kit
provides easy access to the features of the ATtiny1607 to explore how to integrate the device into a
custom design.
The Curiosity Nano series of evaluation kits include an on-board debugger. No external tools are
necessary to program and debug the ATtiny1607.
