Classification according to the type of interface


COM interface and USB interface


1, COM interface also called the serial port, is connected to the desktop computer, is currently being eliminated. The advantage is that the price is low, supporting the brush machine (part of the mobile phone can only use serial line brush machine); the drawback is that the disassembly and pull is extremely inconvenient, does not support the notebook computer, and the transmission speed is also slow.


2, USB interface is the mainstream nowadays. Its advantages are convenience, fast stability, support for all types of computers. The disadvantage is that the price of IC is high, and some data lines do not support the brush function.
