RS485 to TTL Serial Port UART Level Converter Module 25cm It will be appreciated ifThis is a module that allows the TTL interface of the microcontroller to be transferred to the RS485 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. It uses a standard 2. 54 mm pitch
