Frequently Asked Questions

Q: What does the FT232RL USB to UART Serial Adapter Module do?

A: The FT232RL adapter converts your computer's USB connection into a UART (TTL) serial interface. This allows you to communicate with, configure, or program microcontrollers and wireless modules — such as Arduino Pro Mini, XBee, and BTBee — directly from your PC or Mac.

Q: Is this adapter compatible with my operating system?

A: Yes. The FTDI FT232RL chip is supported by drivers available for Windows, macOS, and Linux. In many cases the OS will automatically detect and install the required driver, making setup quick and straightforward.

Q: What is the difference between the 3.3V and 5V modes?

A: The module features a voltage selector that lets you switch its logic output between 3.3V and 5V. Use 3.3V mode when working with modules or boards that run on 3.3V logic (such as most XBee and BTBee modules) and 5V mode for standard 5V Arduino boards — preventing damage from voltage mismatches.

Q: How many units can I order at once?

A: You can choose from single-unit (1 pc) or multi-pack options (5 pcs or 10 pcs), each available with or without a USB cable. Multi-packs are ideal for classroom use, lab environments, or project inventory.
