Introduction: USB-C PD Power Hub for DIY Projects
About a month ago, I showed you how to create a USB power hub using a DC power adaptor like this. One of the suggestions was to use USB type C as the power source and in this post, we will learn how to do just that.
The video above goes over some of the features of USB-C, shows you how to use the trigger board to switch output voltages and also walks you through the build. I'd recommend watching it first to get an understanding of how it all comes together.
Step 1: Gather the Electronics
We will need a USB-C power adaptor that supports power delivery. Along with that we also need a USB-C to USB-C cable, the power delivery trigger board, 4 USB type A ports and some wire.
Step 2: Set the Output to 5V
The video tells you how to use the trigger board but here's a summary:
- Power ON the trigger board by holding down the switch. This will put it in the programming mode.
- Press the switch until the RED LED is switched ON. This selects the 5V output voltage.
- Long-press the switch to set this. The LED should then switch OFF.
- Un-plug and then plug in the board again. The LED should be RED and the output voltage should be 5V. Verify this using a multimeter.
Step 3: Print the 3D Model
I've designed a custom 3D model for this build and you can obtain the files by using the following link:
Step 4: Wire the Ports
Now that we have a 5V power source, we need to wire the output to the USB type A ports. Use the enclosure as a reference for the port locations and add wires of suitable lengths to each of the breakout boards. Then, wire them to the trigger board by using the reference diagram.
Step 5: Complete & Test
The next step is to add the ports to the enclosure, glue them in place and attach the top cover. The enclosure has a lip/groove feature which will hold it together, but if not, you can also add some glue. I'd highly recommend measuring the output voltage and polarity across all the ports once you've completed the build. You can do this by using a USB breakout board and a suitable cable.
That's how easy it is to build this power hub. If you want to learn how to build simple DIY projects like this one, then please consider subscribing to our YouTube channel or following us on social media as that helps a lot.
