7Semi FT234XD USB to UART Isolated Converter Module
The 7Semi USB to UART Isolated Converter Module is a high-reliability serial communication interface designed for safe and stable UART connectivity between computers and embedded systems. Combining the trusted FTDI FT234X USB-to-UART controller with the Texas Instruments ISO6721D reinforced digital isolator, this compact module delivers high-speed isolated communication while protecting connected systems from ground loops, voltage spikes, and electrical noise.
Designed for developers, engineers, industrial automation systems, and embedded applications, the module supports baud rates up to 3 Mbps and offers selectable 3.3V / 5V UART compatibility. The integrated galvanic isolation rated up to 3000V RMS ensures robust communication in electrically noisy or high-voltage environments.
With a modern USB Type-C connector and FTDI driver compatibility across major operating systems, the module provides true plug-and-play functionality for programming, debugging, sensor interfacing, industrial communication, and isolated serial development applications.
