Now thats all good and well but lets now focus on USB type C!
After A lot of cutting trough plastics and heating up the connector to meld the hot glue. I’ve finally got a clean PCB. Then using the BigClive photo reverse engineering program I’ve managed to figure out what does what.
As you can see this one has 4 10µF filter capacitors between Ground and VBUS. And a 5K resistor between the CC pin and the Ground pin. this indicates to the device that it’s a OTG device. And that it should generate a 5volt supply on VBUS.
So now we can make our own USB C to micro adaptor cable.
And now you can make your own USB C OTG cable. I did this teardown so that no one else needs to sacrifice a 15€ USB cable. I’m also looking in to other uses of the USB C connection. So please stay tuned for some more USB C specials.
