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.
