TTL to RS485 module Hardware automatic flow control module serial port UART level mutual conversion power supply module 3.3-5V

Single -chip Machine TTL to RS485 module 485 rotation port UART level -to -hardware automatic flow control

SunlePhant

3.3V and 5.0V power supply and signal -compatible RS485 automatic flow to the control module

No need to "close-hair" control, using this module is as simple as your operation serial port

All of the original imported chips, the performance is very stable, industrial design, 1 year of warranty!

This transparent module realizes the interoperability of the TTL signal and the RS485 signal, but everyone must know that 485 is a half -work communication. This communication method can achieve two -way communication, but it cannot be carried out at the same time in two directions. It must be at the same time. It must be necessary. It must be.Take turns alternately; that is, each end of the communication channel can be a sending end or a receiving end, but at the same time, the information can only have one transmission direction.

Potter rate: support 110 ~ 128000bps

Module highlights:

(1) Width range of power supply: 3.3V ~ 5.5V

(2) Compatible with 5.0V signals 3.3V

(3) Using the original imported chip, industrial-level design, strong anti-interference ability, and more effective 485 lightning protection design, can be used in the industrial scene and harsh environment in the wild. The working temperature is -40 ° C to+85 ° C ° C, The transmission distance can reach a test of a cable of 850 meters of 2*1.5, it is recommended to use it within 800 meters. Please add more than 800 meters.

(4) Using half -hole process design, the thickness of the board is 0.8mm, it can be easily used as a child's panel or welded terminal

(5) Have RXD and TXD signal indicators.

(1) This module fully considers the lightning protection design and anti -interference design of the 485 bus. When transmitting at the field of the field, connect the module's "connecting the earth" to the earth, which can play a good role in anti -interference and lightning protection., Make the 485 bus safer; the indoor short distance transmission can not be connected to the earth.

(2) Use a standard 2.54 -spacing design to facilitate your second development

(3) With 120 euros matching resistance, short -connect R0 can enable the resistance to match the resistance. It is recommended to be short -distance during long -distance transmission.

(4) Support multi -machine communication, allowing the bus with up to 128 devices

(5) This module can be combined with heat plugging, and there will be no other 485 chips that appear to be bornediam.

(6) Paper copper in large areas to prevent signal interference
