I made my own USB Type C module, with a port that can successfully request 5 volts from the USB Type C port on my power bank. The cheaper and more basic USB Type C modules I got could not do that -- they were missing resistors that "request" the voltage from the port. My design also features an LED and mounting holes.

If you're designing your own typec port, then you might want make it PD compatible as well to deliver higher voltages like 9v and 12v, It'd be super useful
Yes, that's coming eventually
@@LeftyMaker Awesome!
This is a great idea. For my future projects, I'm also using USB-C type connectors. By the way, there is a nice documentation about the USB-C, there is so much that you can do with them.
Yup, I agree. And the documentation on USB is overwhelming. I went over it
To make it even better, you'll need a PD sink chip to get 20V😅
That's for another video ;)
This is perfect. The only 'improvement' I could possibly make, is making it "fully USB Type C" compliant with some more chips, that would allow you to set the voltage for projects that need it. And that would be another project entirely. This one is just fine, for what it does. A simple 5V@2A is absolutely fine for a ton of things.
I am planning on making that one day. The chip I wanted to use wasn't in stock for assembly
Neat video, panel mount sockets truly are the best.
I grew fed-up with USB-C power delivery standards and decided to make my own power negotiation standard for higher-power use, being much more flexible too. My circuit uses 7W2 D-sub connectors, with four of the inner pins used for UART communication. It won’t be limited to fixed voltages like USB C, rather anything between 5V and 50V. It will be compatible with parallel loads and series sources. It will be capable of delivering constant-current and constant-voltage outputs. The cables need no chips inside them at all, you just need a PCB with microcontroller at each load and at each source. Both boards measure voltage, the source board measures current, and the load board has a transistor with which to turn the load on and off.
Going to get them made by JLC after one last look-over of the design.
Great project and very useful. For an improvement, you might be able to source a right-angled connector to mount it flatter to the board which would allow you to use it on the edge of a thinner device/project
Yes, that's an option, but those connectors aren't as long. They would be suitable for thinner enclosures made of plastic. Still, it's great having options!
I like these kind of videos.
I also like that you provide links to all you do as well.
Thank you 🙂
Thank you for the support!
The metal type with PCB I recommend using it
Yes, they all work okay as long as you don't need the CC pins
You can find a board with design almost like yours inside e-cigarettes. And they can charge li-ion cell also!
Interesting. Didn't know that
I just recently found out about the components that can be harvested from discarded disposable vapes. I’d love to get my hands on some street lithium, though it doesn’t help that I live in literally the most rural town in my state, so it’s extremely hard to come by (I suppose that’s a good thing though, as it’s litter after all).
@@ebbamb At least you don't have the intense smell on your fingers and all around your workspace for days after harvesting the parts. Those liquids are pure hell. Pure mango ice hell.
@ebbamb yeah, I'm not a fan of those either. I think the disposable type should be banned
those things also draw air through usb-c socket
The rating on the powerbank for the amps should be while maintaining at least 4.95v or so
The powerbank measures the voltage at its end, not across the load. It isn’t surprising that there was a few hundred millivolts dropped across the cable, PCB, and connectors.
Waiting for a CB band carrier wave generator circuit, using ASK protocol for long range digital communication... (Because the currently available modules have really low range)
Not an expert here, but would LoRa work?
Where can I buy some of those USB-C modules you got made?
I think the closest thing you can buy is this, and you have to solder the resistors yourself:
a.aliexpress.com/_EI72AKD I also believe this Adafruit module will work well: www.adafruit.com/product/4090
Can i buy it, i neededs for enclose project. Many thanks.
Perhaps, but I guess the shipping is going to cost a ton. I left alternative shopping links under a previous comment, but if you want mine specifically, let me know.
I wonder... why not a smallest possible horizontal breakout board with just the resistors in place and output pads? For example: the USB C Arduino Nano is laid like that, so what's the issue? Does horizontally not make it reversible?
It is horizontal, but the connector doesn't go through anything but the thinnest enclosures, and the mouting holes (if there are any) are 90 degrees relative to the panel. It works in some instances, of course, but not in mine.
@@LeftyMaker By "horizontal" I mean parallel to the connector and not perpendicular (like the USB C Arduino Nano as I said), doesn't that way save more space and allow for thinner cases? Of course, a solid mounting is another story.
@@lucario4483he uses wood enclosures, the stick-out from common horizontal connectors would require too thin of a panel. Furthermore, being only mounted on one side makes it less robust.
A cool Idea would be a USB-C female to male cable / adapter for using USB-C PD to normal USB-C
Hey man I missed your videos
Too many ideas, too little time :)
Idk video came on right time right topic
The algorithm knows you well :)
Can to explain adrino uno 😊
Honestly, not an expert there, but GreatScott has good tutorials
