The FT231X is a USB-to-serial UART interface IC from FTDI Chip. It converts USB signals to asynchronous serial (UART) and vice versa. Key features:
Common applications:
| Operating System | Official Driver Link | Notes |
|----------------|----------------------|-------|
| Windows 10/11 | https://ftdichip.com/drivers/vcp-drivers/ | Download "setup executable" (CDM v2.12.36 or newer) |
| Windows 7/8 | Same as above | Use legacy v2.12.28 if needed |
| macOS (11+) | https://ftdichip.com/drivers/vcp-drivers/ | Look for "macOS D2XX" + VCP driver |
| Linux | Built-in (kernel: ftdi_sio) | No download needed; see kernel section |
| Android | Not officially supported | Use USB Host mode with OTG cable |
Direct Download (Windows D2XX + VCP Combo):

(Always navigate from ftdichip.com to verify the latest version.)
The Virtual COM Port (VCP) driver emulates a serial port. FTDI also offers a D2XX driver, which provides a direct DLL API for faster, lower-level control.
When to use D2XX:
You can install both VCP and D2XX – they coexist. The D2XX driver is included in the same CDM installer package (Windows) or as a separate download for macOS/Linux.
After installing the driver via the official ft231x usb uart driver link, confirm functionality:
FTDI chips are known for their longevity, but older drivers can conflict with newer hardware.
Verification: Open Terminal and type ls /dev/tty.usbserial-*. You will see a device like /dev/tty.usbserial-ABC123.
