Info on various hardware components

I bought various components from AliExpress, and sometimes they lack info. I’ve added info about them here:

USB-C decoy breakouts: 5V 9V 12V 15V 20V adjustable 3A PD/QC multi-protocol decoy fast charging boost module TYPE-C USB interface


  • Supports multiple fast charging protocols
  • Maximum support 3A
  • TYPE-C port power supply
  • Support multiple fast charging protocols: PD3.0/2.0, QC3.0/2.0, FCP, AFC
  • PD/QC multi-protocol decoy 5V, 9V, 12V, 15V, 20V voltage adjustable

The manufacturer has said that this is the truth table:


This basically seems to be the same truth table as the original USB PD decoy, except the logic levels are inverted (high becomes low and vice-versa), and SW1 in the original is M3, SW2 is M1, and SW3 is M2. Pretty convoluted, but it works.
