Connect your computer to RS485 devices easily with this USB to RS485 converter adapter. It’s a straightforward way to bridge the gap between modern USB ports and the robust RS485 communication standard, commonly found in industrial equipment, sensors, and control systems. Based on the widely used CH340 (or similar) chipset, this adapter typically installs as a standard COM port on your system (drivers may be required), making it compatible with most serial communication software. The screw terminals provide a secure connection for the RS485 differential pair (A and B lines) and ground. Handy LEDs usually indicate power and data activity. Great for DIY projects involving long-distance serial communication or interfacing with multiple devices on a single bus.
