Curiosity Nano is an evaluation platform of small boards with access to most of the microcontrollers I/Os. The platform consists of a series of low pin count microcontroller (MCU) boards with on-board debuggers, which are integrated with MPLAB® X IDE and Atmel Studio 7. Each board is identified in the IDE. When plugged in, a Kit Window is displayed with links to key documentation, including relevant user guides, application notes, data sheets, and example code. Everything is easy to find. The on-board debugger features a virtual serial port (CDC) for serial communication to a host PC and a Data Gateway Interface (DGI) with debug GPIO pin(s).
