1 pcs TTL turn RS485 module 485 to serial UART level mutual conversion hardware
2,88 €
This module can realize the mutual conversion between TTL signal and RS485 signal, but 485 is half-duplex communication. Fully consider the 485 bus lightning protection design and anti-jamming design, long-distance transmission in the field, the module's "earth" side access to the earth, can play a very good anti-jamming and lightning effect, 485 Bus more secure; indoor short distance transmission can not access the earth.
