3.3 Power Supply

The kit is powered through the USB port and contains two regulators for generating 3.3V for the debugger, and an adjustable regulator for the target. The voltage from the USB connector can vary between 4.4V to 5.25V (according to the USB specification) and will limit the maximum voltage to the target.

The following figure illustrates the power supply system on the PIC32CM JH01 Curiosity Nano+ Touch Evaluation Kit.
