Read More…With this breakout of the STUSB4500, you can power all of your devices and electronics projects. From Arduinos to Laptops, USB-C Power Delivery can provide up to 100W (20V @ 5A).
This device can store 3 PDOs (Power Delivery Outputs), and upon connection it will attempt to negotiate the highest of these 3. This means that it can operate as a standalone device, without the need for an external microcontroller. The PDO negotiated is shown by the following colors. By default, the device has the following PDOs:
| PDO1 | PDO2 | PDO3 |
|---|---|---|
| 5V @ 1.5A | 15V @ 1.5A | 20V @ 1A |
| Blue | Green | Red |
There is also the option to change these stored values, and if you select the Custom PDOs Option, I can program the board to set these custom values for you.
The device can also be connected to a microcontroller, to allow on the fly negotiation of the PD contract. To do this the device just needs to be connected via I2C according to the pinout below. Libraries for Arduino exist and are quick and easy to use.
*Output power is limited by the capability of your charger
