The PDTricker Quick Cost Deception Software by Muse Lab connects to a USB-C PD supply, and may produce voltages on an output USB-C port of 5, 9, 12, 15, and 20V. Voltage picks are made through an onboard button, and indicated by a sequence of LEDs. Code that runs it’s obtainable on GitHub, together with the schematic in the event you’d like to look at the way it works. It’s based mostly on the CH224K chip, although the datasheet there seems to be in Chinese language.
One may understandably be nervous about utilizing a USB-C to USB-C “tricker” inline with costly electronics, and/o or leaving it unattended. The place it will appear to shine, nonetheless, can be for take a look at purposes, the place you don’t need to drag out a full featured DC energy provide, and a 5/9/12/15/20V supply can be adequate. For this objective, the system may be ordered with a USB-C alligator clip cable, permitting you to energy up that motor (or different factor) that you simply need to take a look at at your desk with an Arduino.
Impressively, the system is ready to ship 5A at 20V, although this may after all rely in your energy provide. It might additionally has a pair of VOUT/GND by means of holes, on which you’ll be able to solder your personal leads in the event you favor to forgo the USB-C output altogether.
