#9 Making USB-C deliver 5V

Показать описание
UPDATE:
I figured out the reason that one cable is not working: the usb-c connector I'm using has CC1 and CC2 lines shorted together, so you have to cut one of them off and solder its own resistor. Video update:

TL;DW: cut the connection between CC1 and CC2, then add a separate 5.1k resistor to CC2.

USB-C cables/devices are complicated. This was my attempt to simplify one aspect: how to get 5V from a usb-c cable.
I bought these connectors on AliExpress. Out of the box they only work with USB A to USB C cables, so they require some modifications before you can use a pure USB type C cable with them.

Excellent video. I like it when you show your difficulties, it's much more useful than videos that pretend that everything is easy.

It looks like you only added the 5.1K resistor to one of the CC pins. Doing this will cause a USB-C to USB-C cable to work in one orientation but will not work when the connector is flipped 180deg. C to C cables only have one CC wire which allows for power negotiation as well as for determining connector orientation by observing which CC pin has a connection and which is open. You need to add a 5.1k to both CC1 and CC2, or you can also short CC1 and CC2 together, then use one 5.1k to ground. Shorting the CC pins is not normally done but in a simple power application like this, it's not a problem.

I realize this video is a couple years old now, but thought that explanation may help someone who is confused by this.

Thank you so much. This is exactly what I was looking for.

I wish USB C was sized as USB A then each user could "do something" and it's getting popular now with visible pads.

Well you just soldered the resistor just to one of the CC pins, did you try reversing the cable? That's why you could see in the diagram you found on the internet that both CC lines must be pulled down via their respective 5.1 kOhm resistors

To the USB-C designers, why? Just why? Does everything have to be so difficult?

Exactly what I was searching for. Did you check how many amps @5V can you draw using this method ?

The usb type c module still works, but cannot be connected to new phone. I make one, the xiaomi mi5 still some time use quick charge, the mi mix2s can not be connected at all. But i dont know this mod would work

I have an Alienware Tactx keyboard I’m converting to USB C in for a removable cable.
Gonna have to try this when ever the new break out boards arrive.

Even though I’m using an A to C cable there’s no power. A few days ago, using the tester board I found, I grounded CC and the lights came back. Still no keyboard inputs, trying to find a resistor that will work now.

It’s being a real pain because this keyboard has double the wiring, should I disconnect the wiring and run the internal wiring to a hub internally? Or would just the resistor work?

Muito obrigado por passar seu conhecimento sobre isto, que Deus vos abençoe!

so if i just use USB-C to USB-A(usb2.0) charge+data cable without any modified to the breakout board will ut stil work?

I got one usb board and the resistor was 56kohm. Think designer stuffed up.

On cc1 and cc2 what would I need to do to make the usb c negotiate 12 volt from pd

Are you able to do PD out of this type C connector? 9v or 12V?

I have had this problem also with cheap usb c boards from aliexpress

Hey. Have you figured out why Apple cable does not give voltages? I'm facing the same problem the other way around (made a USB c to a USB-c cable with resistors on both sides) It does give 5v when plugged into a regular charger, but not Apple charger. I did some digging and found that Apple products have a handshake so they work with MFI products only, not sure though.

Hi! Is there any chance at all I could get your discord? I'm attempting to do a similar project and just have some questions
