Frequently Asked Questions

Q: Which voltage level should I use?

Select based on your device: 5V for Arduino/older microcontrollers, 3.3V for modern boards (STM32, ESP32), 1.8V for specialized industrial equipment. Check your device datasheet.

Q: Is this compatible with Arduino boards?

Yes! Perfect for Arduino Nano, Pro Mini, and other boards without built-in USB. Also works with non-Arduino microcontrollers.

Q: What operating systems are supported?

Windows (XP and later), Mac OS X, and Linux. Drivers available from FTDI official website or included documentation.

Q: Can I use this for simultaneous TX/RX?

Yes, the FT232RL supports full-duplex communication for simultaneous bidirectional data transfer.

Q: How do I program my microcontroller with this?

Connect TX to RX pin and RX to TX pin of your microcontroller. Use Arduino IDE, STM32CubeProgrammer, or your preferred flashing tool. DTR/RTS pins handle auto-reset on many boards.

Q: Is there a warranty?

Yes! 7-day warranty on manufacturing defects covering all defects. Includes full technical support.

Q: What's the maximum cable length?

Standard USB cable (5m) works reliably. Longer cables may require powered hubs or high-quality shielded cables.

Q: Do you offer bulk discounts?

Absolutely! Contact our sales team for wholesale pricing on orders of 10+ units.
