## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by M***A on January 5, 2026*

Worked perfectly with no driver issues

### ⭐⭐⭐⭐⭐ Great for USB to TTL interfacing.
*by A***R on April 7, 2025*

I needed this to program a Nextron LCD display via a USB port. At first, my Nextron screen showed only lines and static. Then I realized the power jumper was set to 3 volts, and the Nextron required 5 volts. After that, no problems. It just works.

### ⭐⭐⭐⭐⭐ FTDI chip is superior to CP2102, pay the extra few dollars
*by S***. on August 2, 2025*

The FTDI drivers are flawless unlike the CP2102 drivers which are old and outdated. Save yourself the headache and trouble and pay 5 more dollars for the FTDI chips, you will thank yourself in the future. The variable voltage selection jumper on this converter is very useful for handling hardware that runs on 3.3V instead of 5V, saving yourself the hassle of buying, owning, and subsequently finding the right voltage TTL reader. The jumpers included on this were also nice. Great value, would buy again, would recommend to anyone looking for a TTL reader. Use case: Reading serial terminal data off an SBC due to bugged OS compilation software (a lot of bootleg, or alternative rpi clones do not have reliable wifi config options when compiling and writing the software to the boot media. Often, these have no video output, so doing any computing becomes impossible. You need one of these to change the settings on the OS after initial boot to connect to your network to SSH into them).
