This module fully considers the 485 bus lightning protection design and anti-interference design. It has extremely high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance. When long-distance transmission in the field, the module is connected to the earth Access to the earth can play a good role in anti-interference and lightning protection, making the 485 bus more secure; the indoor short-distance transmission can not be connected to the earth. With standard 2.54 pitch pin headers for your secondary development. With 120 ohm matching resistance, short-circuit R0 to enable matching resistance, short-circuit is recommended for long-distance transmission. Support multi-machine communication, at least 40 nodes can be connected to the same network. It can be hot-swapped and there will be no signal thrombosis. Anti-interference wiring and copper laying method to prevent signal interference.
Package Includes: 1 x TTL to RS485 Power Supply Converter Board 3.3V 5V Hardware Auto Control Module, 1 x Connection Cable
