Dual USB To Dual UART Converter For Embedded Development And Debugging
The 7Semi CP2105 USB A to Dual UART Converter Breakout is a USB to serial interface module designed for engineers, developers, and system integrators who need two independent UART channels from a single USB connection. Built around the Silicon Labs CP2105 IC, it enables stable communication with 2 serial devices at the same time, making it well suited for embedded development, firmware flashing, console access, and serial data monitoring.
This module is useful in development labs, production setups, and industrial environments where dual channel serial communication improves workflow and reduces cable clutter. With support for Windows, Linux, and macOS through Silicon Labs Virtual COM Port drivers, it appears as 2 COM ports in host applications. It also supports GPIO, handshaking, and flow control, helping users integrate it into applications that require dependable USB to UART connectivity.
Key Features

Dual UART Channels: Provides 2 independent serial interfaces over 1 USB connection for simultaneous communication with 2 devices.
USB Type A Interface: Connects directly to a computer through a standard USB Type A port without needing an additional adapter.
USB To Serial Communication: Suitable for debugging, firmware flashing, console access, and continuous data monitoring.
Wide OS Compatibility: Supports Windows, Linux, and macOS with Silicon Labs driver support.
Voltage Support: Works with 3.3V and 5V logic level systems for broader device compatibility.
Compact Form Factor: Small footprint makes it well suited for test benches, embedded projects, and industrial setups.
Royalty Free Drivers: Uses Silicon Labs VCP drivers so the module can appear as 2 COM ports in PC applications.
GPIO And Control Support: Includes GPIO and UART handshaking support for status and control functions.
