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.

Project specification

  • USB Data passthough
    • USB 2.0
    • USB 3.1
  • Voltage output available
    • Banana-plugs
    • Screw-terminal
    • 100mil pin header
  • USB Communication to PC
  • No loading of the PSU power when connected to a PC
  • Voltage monitoring (1mV accuracy @ >= 1k SPS)
