This module fully considers the 485 bus lightning protection design and anti-interference design. During long-distance transmission in the field, the "ground connection" end of the module can be connected to the ground, which can play a good role in anti-interference and lightning protection, making the 485 bus safer; indoor short-distance transmission can not be connected to the ground

With 120 ohm matching resistor, short circuit R13 can enable matching resistor, short circuit is recommended for long distance transmission
Supports multi-machine communication, allowing access to more than 128 devices on the bus
This module can be hot-swappable without signal plugging.
A large area of copper to prevent signal interference
With RXD, TXD signal indicator, easy to view the data transceiver
The transmission distance can reach kilometers (for the test with 850 meters of 2*1.5 cable, it is recommended to use it within 800 meters, please add repeaters if it exceeds 800 meters)
Using half-hole process design, the board thickness is 0.8mm, which can be easily used as a sub-mother board, and can also be used for welding terminals.
