Twonkie: A USB-PD sniffer/injector/sink based on Google's Twinkie open hardware
A USB-PD sniffer/injector/sink based on Google's Twinkie, re-designed to be manufactured by mere mortals. - dojoe/Twonkie
It uses a four-layer PCB that can be manufactured cheaply by lots of services like OSHPark, and it makes a point to use only leaded parts for easier soldering (though the main microcontroller can optionally be QFN too via a dual footprint). Get the board made via the OSH Park link above, or supply the v2.0 Gerbers in this repository to a PCB fab of your choice, get the parts from Digikey or Mouser or what have you, and follow the Assembly instructions to build the device. As luck would have it, Greg Davill started a project with the exact same goal at a very similar time, so there's now two of us :) https://github.com/gregdavill/PD-sniffer XenGi built a version of Twonkie v2.0 which uses a 0.8mm PCB and industry-standard straddle mount USB-C connectors.
