single-chip TTL to RS485 module 485 serial UART level switch board (D3B5) | Электронные компоненты и

  The whole network only 3.3V and 5.0V power supply, the signal is compatible with the RS485 automatic flow control module

No need to "receive" hair control, use this module with your operation as simple as the serial port

Module Highlights:

(1) 3.3V and 5.0V power supply is perfectly compatible

(2) 3.3V and 5.0V signal perfectly compatible

(3) Absolute use of imported chips, industrial design, anti-interference ability, while the more effective 485 lightning protection design, industrial and field can be used in harsh environments, the working temperature of -40 to + 85 , the transmission distance of up to kilometers (with 850 meters of the 2 * 1.5 cable to do the test, it is recommended to use within 800 meters, more than 800 meters plus repeaters)

(4) with half hole process design, thickness 0.8mm, can be easily used as a motherboard, but also can be used for welding terminals

(5) with RXD, TXD signal indicator, send and receive situation panoramic view

Module Features:

(1)This module is fully considered485busLightning protection designAnd anti-jamming design, In the field of long-distance transmission, the module "then the earth" side access to the earth, can play a very good anti-interference and lightning protection, so that485Bus more secure; indoor short distance transmission can not access the earth.

(2) Using standard2.54The spacing is designed to facilitate your secondary development

(3)have120Europe to match the resistance, shortedR0You can enable matching resistance, long-distance transmission recommended short circuit.

(4) Support multi-machine communication, allowing access to the most128Device on the bus

(5) This module can be hot-swappable and does not appear to be other485Chip hot plug appears the phenomenon of signal death

(6) Large area of copper, to prevent signal interference
