Before we dive into the driver, let's briefly understand the hardware. The FT231X is a FIFO (First In, First Out) USB to UART interface IC from FTDI (Future Technology Devices International). Key features include:
You will find this chip on popular boards like the SparkFun FT231X Breakout, Adafruit FT231X Friend, and many custom PCB designs.
The FT231X USB UART driver is essential software for interfacing with FTDI-based serial hardware. To ensure stability and security, users should avoid third-party "driver updater" tools and download the VCP Drivers directly from the official FTDI website. Proper installation results in a seamless Virtual COM Port experience, allowing for reliable data transfer between modern computers and serial devices.
Here’s a full write-up on the FT231X USB UART driver link, including what the FT231X is, why drivers are needed, and where to find the official drivers.
Most modern kernels (4.x and newer) include the FTDI_SIO driver natively. No download is required. If not auto-loaded:
Q: Is the FT231X driver the same as the FT232R driver?
Q: Does the FT231X work on Windows 11 ARM?
Q: I lost my driver CD. Can I find an ft231x usb uart driver link that still works in 2026?
Q: My FT231X device says "Driver Error" in the Arduino IDE.
