USB Type-B to RS232 Hub Converter 4-Channel
The 4-Channel USB/RS232 Hub Converter is a compact, board-level serial hub that converts a single USB Type-B connection into four independent RS-232 ports using a CH340 USB-to-UART bridge. It offers both DB9 male and pin-header RS232 outputs, per-channel control signals and clear LED status indicators for easy diagnostics, making it suitable for serial device testing, multi-port communication, legacy equipment interfacing and industrial control applications.
