USB Type-C Power Delivery Trigger Board || DIY or Buy

Websites which where shown during the video:

In this episode of DIY or Buy we will have a closer look at a USB Type-C Power Delivery Trigger board. Such boards are used to output 5V, 9V, 12V, 15V or even 20V from a Power Delivery compatible power source. So I will be showing you how such a commercial board works and I will try to create my own DIY version of it in order to see whether it makes sense to DIY such a board or whether we should stick to the commercial solution instead. Let's get started!

USB PD is the best thing since sliced heatshrinks. I've been using it on most of my projects and the convenience is real.

I went into programming after high school / uni but have ever since felt like I need a small-electronics education too. It's kinda fun that you can get that almost for free on youtube these days! You the man!

[Dbert]

Even with „Buy“ as an outcome I think what you are doing is really worth it. I’m learning something new every video. Keep it going this way! 👍🏻

[Electromakerio]

There is something strangely satisfying about plugging a cable into a USB-C port. Unlike USB-A/B, It just so...hassle free!

[IanGrams]

Thanks for making these DIY/Buy videos! I know it's always a bit disappointing when the outcome is buy, but it's very helpful that you did the work to figure that out and shared it with us all 😁

[AabhasLall]

As things get more and more advanced/complex, buy will usually end up being the winner. And buy has been the only choice for mission-critical applications.
But that has never stopped us from tinkering around, and its always a great learning experience. Just like your videos!

Making your own might be a waste of time, but your new understanding of the device is invaluable

[ketandesai]

I suggest TVS diodes on those CC pins. You want to try avoid large transients on cable removals

[elomoto]

I'm watching your content for more than 3 years and I'm amazed how your channel evolved and how the quality of your materials raised. Keep it up!

I remembered glancing at this video 3 years ago. Luckily I remembered it just the other day for a project. You saved me yet again

[masshysteria]

Great video! There's actually an existing trigger IC which is the IP2721 that does all the work without the need for a microcontroller. There are currently two versions: one that can be either switched between 9V or 12V, and another between 15V and 20V by setting a select pin floating or high. If the pin is grounded, it will only output 5V

[kaumohlamonyane]

I've had the idea of somehow probing the pins of the type c, imitate the signal and maybe some day design my own PD powerbank. This video made me think twice about that thought 😅

[protossid]

I can imagine how much effort you have put on the investigation etc. and put that all together into videos, I really appreciate it mate! Thanks, and keep up the good work!

[JohnSmithZen]

2K of RAM to tell a chip what voltage to output....
Great video!

[sAnime]

i just like how he explains it with the notes he takes
my question is what type of pen is that

[PyroRob]

It's amazing how much time we will spend on building something just to see if we can do it, regardless of how much easier it is to buy. I always enjoy learning, but it can get frustrating.

[kienanvella]

Diy would be the preferred method though in instances where you already are using a microcontroller for something else and needed power negotiation (eg in something like a soldering station for a TS 100 iron). If you have a specific use case where going the diy route will reduce part count it could definitely be worth it.

[pculng]

I've wanted to integrate USB Type C in a project and knowing the capabilities of power delivery has made life alot easier. Great video👌🏽

DIY is not the winner but global knowledge improved a lot with this video

[moritzkoslowski]

I made a PCB with STUSB4500 for my PD stuff and that IC works just great and is even simpler. It also comes with more security and features.
