Description

Type_c To 485 Mobile phone USB To 485 MAC OSX OTG To 485 With Source Code CH340

Module Features

• We guarantee that all chips are brand new and original with stable quality.

• With RXD, TXD, power three LED indicators, 485 serial port input protection;

• The chip has a limited slew rate driver, which minimizes EMI and reduces signal reflection caused by improperly terminated cables, so that the error-free signal transmission rate is as high as 10Mbps.

• Receiver input impedance with 1/4 unit load, supports multi-machine communication, and allows to be connected to the bus of up to 128 devices.

• The working temperature of industrial chips can reach -40℃ to +85℃.

• This module can be hot-swapped, and there will be no signal blocking phenomenon that occurs when other 485 chips are hot-swapped.

• With 120Ω terminal resistance (when the line length exceeds 200 meters, it is more stable and reduces the bit error rate);

• Using transient suppression TVS 400W 30KV diode, the overvoltage protection performance is better;

• Use 22Ω current protection resistor, patch design to improve 485 signal integrity;

• Provide RS485 communication and reserve TTL solder joints on the back;

• Large area of copper to prevent signal interference;

• Support multiple baud rates: 300/600/1200/2400/4800/9600/19200/38400/57600/115200/230400/460800/921600, etc.;

Insert the module to automatically pop up the app, configure the parameter point config, GNG is connected to GND; A+ is connected to A+; B- is connected to B-
