Description
The USB-C PD Power Delivery Board serves as a vital component, acting as a controller board that engages in negotiations with USB PD Chargers to determine the desired voltage and current settings according to your preferences.
This versatile board finds application in a wide range of scenarios where USB-C is required to power your project or device. It simplifies the process with a user-friendly DIP switch, enabling you to effortlessly select your desired output voltage or current rating from the USB PD Charger.
The board is equipped with an on-board DC-DC converter, which can supply either 5V or 3.3V based on the selected jumper configuration, delivering around 3.3W of power. For even greater power requirements, you can harness more power from the DC-DC Converter when the USB PD voltage is lower (e.g., 9V, 12V) or by using an external heatsink.
The board offers the convenience of voltage and current selection and monitoring through an I2C interface, accessible via the 4-Pin header. Its compact dimensions (50mm x 35mm), USB-C input, four mounting holes, and LED indicators for USB-C Input, USB PD Output, and DC-DC Converter Output make it a compact and efficient solution for your power delivery needs.
-
Compact Size: 50mm x 35mm
-
USB-C Input
-
Power delivery up to 65W via DIP switch and 100W via I2C command (I2C pullups are not on the board). Please note that the 3.25A setting(via DIP Switch) may not work with many USB-C PD chargers. We have also observed this during testing.
-
An additional DC-DC Converter(TPS54302) is onboard to generate 3.3V 1A / 5V 0.65A output so that you need fewer components on your application board.
-
4x Mounting holes for easy mounting
-
LED indication for USB-C Input, USB PD Output and DC-DC Converter Output.
-
A 2-pin power terminal is provided for easy connection.
-
A 4-pin 2.54mm header connector is provided for the I2C connection.
-
Both connectors will come unsoldered.

DC-DC Converter Output Selection
By default, the 3.3V jumper will be shorted.
If you need 5.0V output, please open the 3.3V jumper pads and short the 5.0V pads. See the image below for the position of the pads.
