Ft231x Usb Uart Driver Link Access

Getting the FT231X USB UART driver link and installing it correctly is essential for anyone working with microcontrollers, industrial sensors, or legacy serial devices. The FT231X chip, developed by Future Technology Devices International (FTDI) , acts as a high-speed bridge between modern USB ports and the asynchronous serial (UART) interface.

The most reliable and secure source for these drivers is the official FTDI website. You should avoid third-party driver repositories to prevent malware risks or outdated software. Official FTDI Driver Page: FTDI Chip Drivers .

Virtual COM Port (VCP) Drivers: These are the most common drivers used to make your USB device appear as a standard COM port (e.g., COM3).

D2XX Direct Drivers: Used for applications that need direct access to the USB device through a DLL. Installation Guide by Operating System

Modern operating systems often handle FTDI drivers automatically, but manual installation is frequently required for custom hardware or older systems. 1. Windows 10 & Windows 11

Most Windows systems with internet access will automatically download the driver via Windows Update when the device is plugged in. If it fails:

Download the CDM Setup Executable from the FTDI VCP Drivers page.

Run the .exe file before plugging in your device to ensure proper configuration.

Alternatively, use Device Manager to right-click the "Unknown Device," select Update Driver, and browse to your extracted driver folder. 2. macOS

Mac systems typically require the VCP driver to be manually installed. ft231x usb uart driver link

Connect the device and check System Information to confirm it is detected.

Download the macOS driver package from FTDI and follow the installer prompts. Users on Apple Silicon (M1/M2/M3) should ensure they download the ARM version of the driver. 3. Linux

Linux distributions generally include built-in support for FTDI chips in the kernel.

Plug in the device and verify it is detected by typing dmesg | grep FTDI in the terminal.

If permissions are an issue, you may need to add your user to the dialout group or use sudo for access. Troubleshooting Common Issues

If your device is still not showing up as a COM port, try these steps: Drivers - FTDI

The is part of FTDI's X-Series of USB to UART interface chips. To use it, you typically need the Virtual COM Port (VCP) drivers, which make the USB connection appear as a standard serial port to your computer. Official Driver Download Link

The most reliable source for these drivers is the official FTDI Chip VCP Drivers Page.

Windows (Standard): Use the Windows Setup Executable (search for "setup executable") for an easy, automated installation on Windows 7 through Windows 11. Getting the FT231X USB UART driver link and

Windows (ARM64): Specific drivers are required for ARM-based PCs (like Surface Pro X) or Macs running Windows via Parallels.

macOS: Drivers for macOS 10.9 and above are signed by Apple and can be found in the VCP table.

Linux: Drivers are generally integrated into the Linux kernel (version 3.0.0-19 and above); separate installation is rarely needed. Quick Installation Guide

is a highly integrated USB-to-UART bridge designed for fast and simple serial communication. It is widely used in hardware development, legacy device upgrades, and industrial controls. Official Driver Links

You can obtain the necessary drivers directly from the manufacturer, Virtual COM Port (VCP) Drivers

: These allow the USB device to appear as a standard serial port (e.g., COM3) on your computer. You can download the latest versions for Windows, macOS, and Linux on the FTDI VCP Drivers page D2XX Direct Drivers

: Used for software that needs direct access to the FTDI chip without going through a COM port. These are available on the FTDI D2XX Drivers page Key Features of the FT231X Data Transfer Rates : Supports baud rates from 300 baud up to 3 Mbaud Full Handshake UART

Getting Started with the FT231X USB UART Driver If you're working with modern electronics, you’ve likely encountered the FTDI FT231X. Part of the "X-Chip" series, this chip is a popular full-speed USB-to-UART bridge used in everything from industrial controllers to DIY Arduino projects. However, your computer can't "talk" to the hardware without the right drivers. Official FT231X Driver Download Link

For security and stability, always source your drivers directly from the manufacturer. Official FTDI Driver Page: FTDI Chip Drivers

Most Common Download: For Windows 10/11 users, use the CDM v2.12.36.4 WHQL Certified setup executable. This "Combined Driver Model" (CDM) conveniently installs both VCP and D2XX drivers at once. Which Driver Do You Need?

FTDI offers two distinct driver types for the FT231X, depending on how your software needs to interact with the device. Driver Type

For macOS (Ventura, Sonoma, Sequoia)

  1. Download the FTDIUSBSerialDriver_v2.4.4.dmg from FTDI’s VCP page.
  2. Open the DMG and run the .pkg installer.
  3. Follow prompts, entering your admin password when required.
  4. Allow System Extension:
    • Go to System Settings → Privacy & Security.
    • Scroll to "Security" and allow the FTDI driver to load.
    • Reboot if prompted.
  5. Connect your FT231X device.

Verification: Open Terminal and type ls /dev/tty.usbserial-*. You will see a device like /dev/tty.usbserial-ABC123.

If not loaded, manually load it

sudo modprobe ftdi_sio

Windows

  1. Download CDM (Combined Driver Model) installer.
  2. Run CDM v2.12.36.4.exe (or newer).
  3. Connect FT231X device.
  4. Check Device Manager → Ports (COM & LPT) → USB Serial Port (COMx).
