The safest, fastest link for 99% of users (Windows 10/11):
Download, install, reboot, and your FT231X USB-UART will be ready.
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 ft231x usb uart driver 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.
Windows (ARM64): Specific drivers are required for ARM-based PCs (like Surface Pro X) or Macs running Windows via Parallels. The safest, fastest link for 99% of users (Windows 10/11):
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
This is a fake/clone chip issue. FTDI's newer drivers (v2.12.28+) intentionally misbehave with counterfeit chips. They will set the PID to 0x0000 or ignore the device. 👉 https://www
How do you know if you need the FT231X driver? Look for these signs:
If this sounds familiar, the solution is a quick driver installation.
The FT231X is a popular USB to serial UART bridge chip manufactured by FTDI (Future Technology Devices International). It is ubiquitous in the hobbyist electronics world. You will find it hiding on the bottom of ESP32 dev boards, acting as the interface for Arduino Pro Micros, or serving as the communication bridge for countless custom PCBs.
Its job is simple but essential: it translates data between your computer’s USB port and the serial (UART) pins on your microcontroller. Without the correct driver, your computer doesn't know how to talk to the chip.
Even with the correct ft231x usb uart driver link, problems can arise. Here are the top solutions:
