Industrial-grade USB to 485 module, the 485 chip is easy to replace, it is more convenient to use when the 485 chip is easy to burn out in the hardware debugging.

Analysis of the USB to 485 solution on the market:
Solution 1: CH341+485; The shortcomings are unstable, which can easily cause the computer to black screen;
Solution 2: PL2303+RS232+RS485; This solution uses PL2303 to convert to a serial port first, and then convert the serial port to 485; the advantage is low cost, but the disadvantage is that there may be instability in industrial occasions and high speed is not suitable.
Scheme 3: FT232+485; Advantages: industrial-grade applications, speed and anti-interference ability are very good
Good, very suitable for industrial control field, personal application. Disadvantages: high cost.
