What are the classification of Android data cable?

The Android data cable is classified according to the interface type:

Divided into COM interface and USB interface.

1. The COM interface, also called serial port, is connected in front of the desktop computer and is currently being eliminated. The advantage is that the price is expensive, and it supports flashing (some mobile phones can only use the serial line to flash); the disadvantage is that it is extremely inconvenient to remove and remove, does not support notebook computers, and the transmission speed is relatively slow.

2. The USB interface is the mainstream. The advantage is that it is convenient for rapid fluctuations and supports all types of computers. The disadvantage is that the price of the IC (local control chip) is slightly higher, and some of the internal data lines do not support the brush function.

The Android data cable is classified according to the chip:

The Android data cable has no IC (local control chip), with IC (local control chip), special chip.

1. Without IC (local control chip): there is no local control chip, you must plug in the mobile phone computer to recognize the line, the price is cheap.

Typical models: Samsung CDMA series, D500 series, Motorola E398 series, V3 series, Nokia DKU-2, NEC N720 series, Siemens 65 series and so on.

2. With IC: with local control chip, the model of ordinary chip is 2303, 2101, 3116, and it will recognize the line without plugging in the mobile phone computer. Because the price of an IC is more than 10 yuan, the price is more expensive than without IC. The principle of the data cable with chip is to convert the USB interface into a serial port and display it on the computer.

3. Special chips: non-ordinary mass chips, common special chips such as DKU-5, CA-42, DCU-11, etc.

Note: Do not mistakenly believe that the quality with IC is good, and the quality without IC is poor. The practice with or without IC is based on the applicable model of mobile phone.
