| May 30 at 18:32 | comment | added | condor12 | Is it really that difficult to put this into practice? I wanted to experiment with an old tablet first and then apply it to newer devices. Thanks for clarifying the number of pins for me. As you mentioned before, and as I suspect, it is not possible to use the connector without connecting the CC pins. Could you tell me where these pins are connected in these modules? You've said that it's possible to do what I have in mind, so could you enlighten me a little? Maybe you could give me some clues. Regarding the USB-C module, how many pins does it actually have? Thank you. | |

You also link to several different boards, so unknown which you have. If you ask for a recommendation, the best way to handle the situation would be to not be in the situation to begin with. Just leave the MicroUSB and forget Type-C would be my recommendation, and you will have an usable tablet. | |
| May 30 at 7:20 | comment | added | condor12 | In this case, since the pins are odd, some sources say the module has 14 pins, while others say it has 24 (I have uploaded photos). I have seen the copper vias on the PCB, and as you mentioned and as I suspected, it cannot work without the CC pins connected. So, I need to add them somewhere. However, I am not sure where to solder the CC pins on the USB-C module. You are right about the parallel connection and the problem with the different connector types and the 5V. Do you have any recommendations on how to handle this situation? | |
| May 30 at 7:20 | comment | added | condor12 | Hello. Thanks for responding and for all the information. Regarding your answer, it does not look like an OTG port. In fact, I tested it before disassembling it, and it is only a charging port (with an OTG port, I would not dare to do what I have in mind). If you see the symbol written on the case, it is the direct current indicator (I have uploaded photos (DCIN)) | |
