I love DIY, and one day decided to replace the male of an old micro USB data cable with a TYPE C male.
So I bought two TYPE Cs online, but it was not easy to connect to the line. When I asked the customer service, I said this was an OTC header and I couldn't charge!!!
returns? It's not worth it. So I studied the principle of TYPE C and searched it and found that a TYPE C charging head can become an OTG header by adding a resistor. That should be the same.
After carefully comparing the difference between the charging head and OTG, there is a major discovery. The only difference is that the position of the resistor on the PCB board is different. This is simple. The resistor is shifted to see if it can be successful--it is really successful!
above picture
above picture is the normal OTG head terminal, the same as the charging head.
The picture above is a normal OTG head, a capacitor, and a resistor. We just need to move this resistor to the empty space.
Movement resistors should be used with a hot air gun. After the solder is melted, use tweezers to push it straight to the empty space in the middle. Do not clamp it up. If it is too small, you can't clamp it. One stroke of the tweezers is against the PCB board. Use the other stroke to move, be careful not to touch the capacitor.
successful!
additional instructions, there are also many types of TYPE C heads, please pay attention to choosing the same OTG or charging head as shown in the picture.
Similarly, if you choose the right charging head, you only need to move the resistor from the middle to the right to instantly turn it into the OTG head, without adding an extra resistor as mentioned on the Internet.
OK, please communicate at any time if you like it.
