USB to RS485 converter RS485 communication module expansion board FT232RL
Function: This module acts as a bridge, converting USB signals from a computer or device into RS485 serial signals. This enables communication between devices that use different communication protocols.
FT232RL Chip: The heart of the module is the FT232RL chip from FTDI. This chip handles the USB communication and provides a standard interface for serial data transfer.
RS485 Standard: RS485 is a robust, balanced serial communication standard commonly used in industrial environments due to its noise immunity and ability to transmit data over longer distances.
Half Duplex: Half duplex means that data can be transmitted in both directions, but only one direction at a time. This is in contrast to full duplex where data can be sent and received simultaneously.
