Parameters:
Operating voltage range: DC 3.0V ~ 30V
Operating temperature range: -40 ℃ to +85 ℃
Baud rate: 110 ~ 256000bps

Module Features:
1) the 485 bus is with lightning protection and anti-jamming function, with high EMC, EMI performance. When using for long-distance transmission in the field, the module EARTH side please connect to the ground, can achieve well anti-interference and lightning protection function; for indoor short-distance transmission, it cannot connect to ground.
2) with standard 2.54 pitch pin
3) with 120 ohm matching resistance, shorted R0 can be enabled to match the resistance, recommended shorted for long-distance transmission.
4) support multi-machine communication, the same network can connect at least 40 nodes.
5) can be hot-plugging, there will be no signal plug phenomenon.
6) using anti-jamming alignment and copper to prevent signal interference.

Package Including:
1x TTL to RS485 Signal Converter Module
1x 2.54 White Socket with 4P Lines
