Know before you buy
Yes, while it is optimized for RFD900 series modems, it functions as a standard USB to TTL serial cable. It will work with any device requiring a 3.3V TTL serial interface.
The cable receives 5V from the USB port, but the data interface operates at a 3.3V logic level. Ensure your specific device is compatible with 3.3V signal levels to avoid potential damage.
Yes, because this cable uses an FTDI chip, you will likely need the standard FTDI VCP (Virtual COM Port) drivers installed on your computer for it to be recognized as a serial port.
The 1.8-meter length is standard for most desktop or field-based telemetry setups. It provides enough slack to connect a modem to a laptop or ground control station without requiring an additional USB extension cable.
No, this cable is unshielded. While it is reliable for standard telemetry and data communication, you should keep it away from high-power radio transmitters or sources of significant electromagnetic interference to maintain signal integrity.
