RS485 to TTL Module Stable UART Serial Port to RS485 Converter Function Module

We will test it before shipment. Reference Weight:0.04kg (0.09lb.) 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-lightning effect, more secure; it can not connect with the ground when the indoor short-distance transmission Using the standard 2.54 pitch design, easy secondary development Has a 120 ohm termination resistors, shorted R0 to enable the termination resistor Support multi-machine communication, allowing access at up to 128 devices on the bus The module can be hot swapped, the signal does not appear dead phenomenon A large area of copper to prevent interference
