Overview

The Microchip AVR64DU32 Curiosity Nano evaluation kit is a hardware platform to evaluate microcontrollers in the AVR DU family. The kit comes with a fully integrated programmer and debugger that provides seamless integration with Microchip MPLAB X.

The kit's array of features, including a variable voltage power supply, dual USB Type-C® connectors, a virtual serial port, and a DGI, facilitates easy integration into a custom design.

The AVR64DU32 Curiosity Nano features two USB Type-C® connectors, one for programming and debugging, and one connected to the AVR64DU32’s USB 2.0 full-speed peripheral.
