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 Microchip MPLAB® X. Each board is identified in the IDE, and relevant user guides, application notes, data sheets, and example code are easy to find. The on-board debugger features a Virtual COM port (CDC) for serial communication to a host PC, and a Data Gateway Interface (DGI) GPIO logic analyzer pin.
