From the project

Small 2-layer fixed USB-C PD power sink with CYPD3177 and 2 pin terminal block.

Small 2-layer fixed USB-C PD power sink with CYPD3177 and 2 pin terminal block.

The board provides a fixed output from USB-C PD (Power Delivery) using the CYPD3177 chipset. It's highly flexible, allowing USB-C Charging up to 15W and USB-C PD up to 100W. Unlike many other chips available, it does not require any firmware nor flashing, and power settings are configured with pullup and pulldown resistors. This design is inspired by CYPD3177-Breakout. Resistors R1 and R2 set the maximum current, which is 2A according to the default values in the schematics. By adjusting the values of resistors…
