Re: Is the 485 interface obsolete
Compared with USB port, the transmission distance of USB port is short, the data transmission rate is high, and the transmission distance of RS485 is long, the data transmission rate is low.
RS485 is mainly used for industrial control, not to transmit large amounts of data.
