# Power-delivery Enabling Widget (PEW)

## Description

Power-delivery Enabling Widget (PEW) is a versatile
USB Power Delivery (PD) trigger project designed to facilitate
power management for external devices, either by acting as a
machine in the middle when connecting to a USB device, or as a basic
PD trigger exposing the power output for other uses.
By acting as a machine in the middle PEW is able to see the requests from a device,
communicating them to a PC for wasy debugging of PD applications.
PEW provides real-time data for voltage, current, and power, which is accessible
through a user-friendly PC application.
