USB to RS232 RS485 Converter

Description

The USB to RS232/RS485 Converter, powered by the advanced CH343G chipset, is a high-performance solution for reliable and seamless serial communication. Designed for industrial, commercial, and DIY applications, this converter ensures stable data transmission, surge protection, and broad device compatibility, making it an essential tool for engineers, developers, and technicians.

Featuring dual interface support, this converter allows users to easily switch between RS232 and RS485 protocols via a toggle switch. With plug-and-play installation across major operating systems (Windows, Linux, macOS), it eliminates the need for complex drivers in most cases.

The converter supports high-speed data transfer rates up to 3Mbps, ensuring smooth communication with industrial machinery, POS systems, barcode scanners, and embedded devices. Built-in TVS protection, self-recovery fuses, and ESD safeguards provide robust durability, while LED indicators (PWR, TXD, RXD) allow real-time monitoring of operation.

Its compact and portable design makes it easy to carry, integrate, and deploy in a wide range of setups, ensuring dependable performance for both field and lab use.
