1pcs TTL turn RS485 module 485 to serial UART level mutual conversion hardware

Details: * The module is fully considered mine design it 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 R0to enable the termination resistor. * Supports 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. * Compatible with 3.3V and 5.0V power supply. * With RXD TXD signal indicator light monitor send and receive status. Specification: *Type:TTL turn RS485 *Color: As Pictures Show *Size: 53*25mm *Quantity: 1pcs Package contents: 1* UART Serial Port to RS485 Converter Note: 1 Only in the whole network 3.3V and 5.0V power supply RS485 signal perfectly compatible with automatic process control module. 2 Without Receiving - launch control this module is as simple to use with your serial port operations. 3 The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness
