Common interface of data line

1. COM interfaces, also known as serial ports, are connected to the back of desktop computers and are being phased out. Advantage is low price, support brush machine (some mobile phones can only use serial line brush machine); The disadvantage is that it is extremely inconvenient to remove, does not support laptop computers, and the transmission speed is relatively slow.

2, USB interface is the mainstream, the advantage is convenient, fast and stable, support all types of computers; Disadvantage is with IC(central control chip) the price is slightly higher, another part of the data line does not support the machine brush function.
