COM interface and USB interface

1. COM interface is also called serial port, is connected to the desktop computer behind, is currently being eliminated, the advantage is low price, support brush machine (some mobile phones can only use Serial line brush machine); The disadvantage is that the removal is extremely inconvenient, does not support the notebook computer, transmission speed is also relatively slow.

2. USB interface is the mainstream, the advantage is convenient and stable, support all models of the computer; The disadvantage is that the price of the IC (central control chip) is slightly higher, and the other part of the data line does not support the function of the brush machine.
