What is a Type-C interface
Type-c indicates the USB Type-C interface, a new form of the USB interface. USB Type-C ports are 8.3mm wide and 2.5mm thick, while Micro USB ports are 7.4mm wide and 2.35mm thick. The Type-C port is slightly larger than the Micro USB port and thinner and thinner than the traditional USB port.
In addition to the thin USB Type-C, other advantages are more noteworthy. If both sides can be plugged in, the fiber can withstand tens of thousands of times of repeated insertion, transmission speed up to 10Gbps, power supply capacity up to 100W, strong scalability in addition to charging, data transmission can also be audio.
The method of converting USB Type-C data cable into OTG data cable has been introduced earlier. In a word, CC pins are grounded with 5.1K pull-down resistance to change the working mode, so that Vbus pins can supply power to U disk, mouse, keyboard, etc. The phone can read files directly from the USB flash drive or copy files from the phone to the USB flash drive. No need to transfer data through the computer, perfect for going out. USB Type-C interface definition, teach you to change the type-C data cable into OTG data cable
Just said that USB Type-C data cable can not only charge data transmission, but also can transmit audio and video, etc. Many Android phones not only replace the traditional Micro USB with Type-C ports, but also eliminate the 3.5mm headphone Jack. This type of phone can only use the Type-C to 3.5mm earphone converter cable to use the earphone. After studying the definition of type-C interface and related data, it is found that the pins corresponding to type-C output audio and received signals are shown in the figure below. Pin 6, 7, and 8 correspond to the right channel, left channel, microphone, and microphone respectively, while pin 1 corresponds to the GND of the headset.
The headphones used by mobile phones are three and four segments with four wires, which are GND (ground), Mic (microphone), L (left track of earphone), R (right track of earphone). Use a multimeter to measure a variety of headphones, most of them are the first connection, only Nokia is the second connection.
In this way, we can put each pin of Type-C in contact with the microphone of the headset and the left and right channels of the headset, and we can make a USB Type-C to 3.5mm headphone transfer cable. Experience the fun of DIY and enjoy the joy of success. Note that the phone's random Type-C cable is completely missing some pinching. Before modification, check whether the required pins are in good condition. In addition, USB Type-C plug pin, manual welding is more difficult. Please do it within your means.
