How to install FT232R USB UART

Wondering why your Arduino app doesn’t detect your usb port. It maybe because the driver is not installed on your Windows computer. You can download the UART driver for free from their website.

On your Windows computer, search for Device Manager. In the image below, it shows the FT232R USB UART was not installed on my computer.

To solver this, you can try to update the driver. Sometimes this is enough to fix the problem.

But if it doesn’t solve the issue, then we need to download the driver from their website: www.ftdichip.com

I found the drive exactly from this URL: https://www.ftdichip.com/Drivers/CDM/CDM%20v2.12.28%20WHQL%20Certified.zip

Download the file and unzip it.

Go back to device manager and update the device with the downloaded driver.

Once it’s updated, it should work properly.
