Industrial USB to RS232/485 Converter FT232RNL with Cable

With this compact USB to RS232/RS485 converter, you can quickly and easily connect serial devices to your computer or embedded system via USB. The module is ideal for applications where reliable communication over serial interfaces is required – whether in industrial environments, building automation, or microcontroller project development. Thanks to the integrated FT232RNL chip, a stable connection with high compatibility is ensured. The galvanic isolation between USB and RS485/RS232 provides increased safety when connecting to industrial devices. Additionally, you can easily switch between RS232 and RS485 mode, making the module particularly flexible. The mounted USB cable makes you ready to use immediately – without additional accessories. The compact dimensions make the device perfect for mobile applications and confined spaces. Whether for debugging, data acquisition, or control applications – this converter module offers you a robust solution for serial communication.

Features:

• The module supports both RS232 and RS485 communication via a single USB port.
• Communication is handled via an integrated CH343 USB UART chip, known for high compatibility.
• Thanks to galvanic isolation, a secure connection between your USB device and the external serial system is ensured.
• Switching between RS232 and RS485 is done easily via a DIP switch on the board.
• An LED indicator shows you the operating status of the serial interface.

Application Examples:

• Connecting a Raspberry Pi to an industrial controller via RS485
• Data transmission from a GPS module via RS232 to a PC
• Debugging a microcontroller with a serial interface
• Use in a home automation system for control via RS485
• Connecting measuring instruments to a control system in the laboratory
