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.
