Want to replace your non USB-C power/charge cables for USB-C ones? This project lets you do just that!
The board uses a Cypress CYPD3177 which will communicate with the USB power supply over USB-PD and negotiate the desired voltage and current. The voltage and current requested is set using 8 resistors that can be easily hand soldered to customize each one.
The available voltage ranges are: 5V, 9V, 12V, 15V, 19V, and 20V. You can set a minimum and maximum voltages in order to get the highest available or select just a single one so that you always know what you're getting.
The available currents range from : 0A to 5A in 0.25A increments.
If the selected voltage or current is not available, a red LED lights up and the output is disabled.
Trying to figure out which resistors to put where? Don't worry! I put together a nice calculator to do it for you. Check it out here!
This board is designed to handle 5A @ 20V, but has only been tested to 3A @ 20V, so proceed with caution if you need the full 100W.

Questions
How big is the Usb c power PCB?
It measures 36 × 12 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb c power use?
26 parts, built around the IRF9358TRPBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Usb c power KiCad files?
From the alvarop/usb_c_power repository on GitHub, at the commit this page was made from: the board is usb_c_power.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb c power design in my own project?
Its repository states no licence, so its author keeps all rights: ask alvarop before reusing the design.
