TTL Turn To RS485 Module 485 To Serial UART Level Mutual Conversion Hardware Automatic Flow Control 3.3V/5V Power Supply Module

説明

This product is a TTL to RS485 module, designed with industrial grade design, fully considering 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; Indoor short-range transmission can be carried out without connecting to the ground.
