Perfect for my Aurdino

Worked absolutely amazing on my aurdino! Couldn’t have been more please. USB port, connectivity where great.

It worked to mate rxtxlite to my uSDX+ V2

I used one of these to adapt my cellphone with the rxtxlite android app to my uSDX+ V2 qrp transceiver. Everything went together easily, and worked perfectly. Now I can change bands, modes, and adjust frequency with the phone instead of the buttons on the radio. Cheap and easy to do! I would recommend.

Works great, the 3v/5v pins are confusing

Flashed ESP on a bunch of devices and it works.- Not sure why you need 5. Would rather see them include instructions- Jumper is a bit confusing.- Did get the job done

If it is what you need, it's great.

I know these things for a need of programming hardware or something. If your looking for a USB to Serial USB to TTL CH340, this will do the job and it worked perfectly the first time. No problems at all. I put ease of use to a 3 star because for the NooB, it's not strait forward on how to use it.Well worth the money if you need it...

There is no DTR/RST pin on these. Cannot use to upload sketch to Arduino

These were a huge disappointment. They will connect fine to an arduino for serial output but will not upload any sketch. These are missing a DTR/RST pin for uploading. I wanted to use these to reprogram an Arduino nano after sealed in a case but they can't happen.

Work great with my esp32cam

If you're in the market for these, you're probably comfortable with attaching wires and reading schematics. I needed these to connect a windows 10 pc to an esp32cam. I attaching the 3.3v to my esp's 3.3v I also connected the 5v to my esp's 5v. Also connected ground, tx, and rx. Used the jumper for bridging the programming pins on the ESP32CAM. Couldn't figure out vcc and didn't use it. There are lots of instuctions out there, but this worked for me.

Worked fine, with a caveat. MacBook USB port to program ESP32-CAM

I tried these because they were cheaper than the typically cited FTDI converters. Online, users post about having issues connecting to ESP32-CAMs. I worried using these would complicate things. Initially, these failed to upload properly at the default 921600 baud (using the Arduino IDE). However, they worked when fine when I cut back to 115200 baud. It might have worked at a in-between rate, like 460800, but i didn't try. I can't blame these convertors, because people were having the same issue with the FTDI type converters too.Clarification on use:These have a jumper to choose between 5V and 3.3V logic levels. This doesn't affect the voltage of the 5V or 3.3V output pins, just the TX/RX logic levels. The ESP32 needs 3.3V logic levels, but people say it programs more reliably if you use its 5V Vcc pin. I set the jumper for 3.3V, but connected the 5V output pin to the 5V Vcc of the ESP32, letting it regulate its own supply. This worked very reliably, for me.

Actual range 3.3-3.8V, or 4.5-5.5V

I had no problem with drivers. The operating range in 3.3v mode is just high. Another seller has them listed as switchable between two ranges: 4.5-5.5V and 3.3-3.8V. When unjumpered, it is in the lower range, but it still may be too high for 3.3V devices. (I wanted to use these with SBCs. If the current is low enough, it might be ok, but I don't want to risk it.) That's the only issue I have, really, but the rxd pin being high initially makes it worse. I am returning them. I suggest they change the description to give full voltage ranges and possibly current ranges or explanation.
