Compact USB-to-TTL serial hub that provides four independent virtual COM ports from a single USB connection. Ideal for connecting multiple TTL serial devices while saving space, reducing wiring, and minimizing USB port usage on the host system.
The C47Lab TTL Serial Hub is a compact USB-to-serial interface designed to connect up to four independent TTL serial devices through a single USB port.
Once connected to the host computer, the hub enumerates as four separate virtual COM ports, allowing each TTL device to be accessed independently by the operating system and by standard serial communication software. This makes it possible to integrate multiple serial peripherals while using only one USB connection on the host.
By replacing several individual USB-to-TTL converters with a single compact board, the C47Lab TTL Serial Hub reduces wiring complexity, saves valuable space inside embedded systems, and minimizes the number of USB ports required on the main computer, companion computer, or development platform.
It is especially useful for UAVs, robotics platforms, embedded test benches, autopilot systems, telemetry devices, sensors, and other applications where several TTL serial links must be managed in a clean and reliable way.
