A compact USB power detector that displays charging voltage and current simultaneously on a single screen. Useful for monitoring power consumption of Arduino boards, USB devices, sensors, and other modules in real time.

The detector sits inline between a USB power source and device, with one input and two output ports. Output I supports both data communication and charging, while Output II provides charging voltage output only.
