High - Quality Microcontroller TTL to RS485 Module Effortless 485 to Serial UART Level Conversion with Automatic Control

Baud rate: supports 110-12800bps

​ ​Module: (1) Wide power supply range: 3.3V~5.5V

​(2) 3.3V and 5.0V signal compatibility

​(3) Using original imported chips, industrial grade design, strong anti-interference ability, and more effective 485 lightning ​protection design, it can be used in harsh industrial and outdoor environments. The working temperature is -40 ℃ to+85 ℃, and the ​transmission distance can reach kilometers (tested with 850 meters of 2 * 1.5 cables, it is recommended to use within 800 meters, ​and if it exceeds 800 meters, please add a repeater)

​(4) Designed using a half hole process, with a board thickness of 0.8mm, it can be easily used as a daughter mother board or ​welded to terminals

​(5) Equipped with RXD and TXD signal indicator lights,providing a panoramic view of transmission and reception conditions ​ ​

Module features: ​(1) This module fully considers the lightning protection and anti-interference design of the 485 bus. When transmitting over long ​distances in the field, connecting the "grounding" end of the module to the ground can play a good role in anti-interference and ​lightning protection, making the 485 bus safer; During indoor short distance transmission, there is no need to connect to the ​ground.

​(2) Adopting a standard 2.54 spacing design, it facilitates your secondary development

​(3) Equipped with a matching resistor of 120 ohms, short circuiting R0 can enable the matching resistor. Short circuiting is ​recommended for long-distance transmission. ​

(4) Supports multi machine communication, allowing connection to the bus of up to 128 devices

​(5) This module can be hot swapped without the signal jamming phenomenon that occurs with other 485 chips during hot swapping

​(6) Large area copper laying to prevent signal interference
