Much Better than Cheaper Versions
I needed to connect to a serial device that operated at an unusual baud rate, and bought a number of USB/UART converters. This one is hands down the best, probably because it uses a real FTDI chip. Problems that I have had with other converters: (1) problems with higher-speed and non-standard-speed communications, (2) vcc problems (voltage not matching 3.3V, and dropping further with the slightest current draw), (3) difficult-to-read labeling.This converter worked flawlessly the first time. It has a convenient ribbon cable which is extremely helpful. It has a selectable voltage from 1-5 volts, and I believe (based on some data sheets) that I was consuming 250 mA at 3.3V.Anyway, despite the fact that it is a bit pricy, it just worked, which ultimately saved me a lot more money than the cheap ones. I liked it so much I ordered a second one.

Not the cheapest, but rock solid and great voltage flexibility.
Works perfectly. Flashed four ESP8285 devices with ESPHome the first day I got it and had absolutely no problems. I bought a cheap programmer directly from a Chinese reseller website and spent hours debugging issues before I concluded it was a bad programmer; this FTDI adapter immediately fixed my issue. Worked without additional configuration when plugged into my laptop running Bazzite Linux. Instructions include a QR code for Windows drivers, which I installed then tested this adapter to confirm it works on a Windows machine as well.

GREAT USB adapter with all RS-232 signals, also included interface cable!
GREAT USB adapter with all RS-232 signals. Used to modulate a DTR pin from a USB port with excellent results - solved a problem I'd been working with for WEEKS! Not mentioned was that an approximately 11-inch interface cable is also supplied, and the unit came with TX and RX pins shorted with a jumpter to make it easy to see the interface was working.I will definitely recommend this product to others!

Works very well no driver issues or connectivity issues at all!
Works very well I haven’t had any driver issues or connectivity issues at all. These ttl uart adapters can be used for a very wide range of things. I made my own OBD 1 diagnostic cable was mine for older Chevrolet vehicles.

Great adapter.
Worked great with my raspberry pi pico and Zero 2 W. I did have to manually install the drivers on my tablet running windows 10 using the exe from their site while my desktop automatically installed them under windows 11.

Nice product
Worked well. I like the configuration for input voltage for logical "1"

Does its job well, made well
Worked perfectly to act as an interface to reprogram a home energy monitor device. Built well, versatile, no issues when using in a Win11 environment.

The Only USB Serial Adapter to Have!
This serial adapter is awesome. It's plug and play with Windows 11 (my old one wasn't and wouldn't work anymore). The multiple voltages are awesome. It comes with a jumper for a loopback by default and has an adapter cable with it. It's everything you could dream of in a serial adapter.

Works out of the box!
Having wasted £5 on a cheap USB to serial converter on a popular online auction site only to find the drivers available wouldn’t work at all, this worked straight away with OSX Monterey - supported by drivers in the Apple kernel so no driver downloads required. The variable voltage level will be handy, and the clear plastic casing gives it a degree of protection meaning it should last a while. As with most things, to get what you pay for! Recommended.

信号レベルが選べるのが良い。多用途で使えるので、1本備えておきたい。
パソコンとモジュールの通信用に購入。色々なモジュールで、ちょくちょくこの類の製品が欲しくなるため、多電圧に対応した製品をチョイス。重宝してます。単電圧だけ対応であれば、もう少し安い製品もありますが、日常的に電子工作等で多用する人は、これ一本あると便利です。手のひらサイズのケースにて保護されているので取り扱いも楽です。USBはオスコネクタでPCに直付けできますが、UART側の配線が長くなるので、長距離で繋ぐと高いボーレートでの通信は厳しいかも?
