Main Features

Features: 
 
(1) The module is fully considered mine design, long-distance transmission signal 485 in the wild, the module "Connected to the ground" terminal is connected to the earth, can play a very good anti-jamming and anti- effect, more secure; it can not connect with the ground when the indoor short-distance transmission. 
(2) Using the standard 2.54 pitch design, easy secondary development. 
(3) Has a 120 ohm termination resistors, shorted R0to enable the termination resistor. 
(4) Support multi-machine communication, allowing access at up to 128 devices on the bus 
(5) The module can be hot swapped, the signal does not appear dead phenomenon. 
(6) A large area of copper to prevent interference.
(7) Compatible with 3.3V and 5.0V power supply. 
(8) Compatible with 3.3V and 5.0V signal. 
(9) Absolute using imported chips, industrial design, anti-interference ability, while using more effective mine design can be used in the industrial field and harsh field environments, the working temperature of -40 ° to + 85 ° transmission distance up to 1 kilometer (made with 850 meters of cable F1.5 tests recommended in the 800 meters, more than 800 m, please add repeaters). 
(10) Semi-hole pads, onboard module, thin PCB, having a thickness of 0.8mm. 
(11) Has RXD, TXD signal indicator light, monitor send and receive status.
