USB 3.1 Type C to Type A Adapter with PD

This board is an universal USB Type C to Type A (male) converter that is capable of USB 3.1 Gen 2 data rates.
The PCB is able to extract the USB PD signal and output the voltage to a screw terminal.

Usage examples

Implemented in current revision


Handle the USB PD negotiation and extract power from a USB PD power supply
Act as a USB 3.1 USB Type A to Type C Adapter
Act as a passive USB 2 Type A to Type C Adapter
Upgrade a Laptop that has a USB 3 Type A port to a Type C port and charge the Laptop via 20V USB PD (DC plug connected to the screw terminal)


Note: This features are supported by the hardware revision v1.0, the firmware is not implemented yet.

Planned for future revisions


Act as a DFP to provide USB PD power to a device (the voltage higher than 5V is inserted via the screw terminals)
Automatically switch between the different roles (UFP and DFP) depenting on the connected devices
