RS485 to TTL UART Converter Module
RS485 to TTL / TTL to RS485 converter is a module that allows the TTL interface of the microcontroller to be transferred to the RS485 module / MAX485 module. It is generally used for industrial automation. This module adds lightning protection design and anti-jamming design. When we use it in the field and carry out long distance transmission, we can Connect the GND end of the module to the ground so that lightning protection and anti-interference can be achieved. This Max485 to TTL module is online in Pakistan at electrobes.
