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.

Jumper for +5V or +3.3V; reliable CH340

These are by far my favorite USB/TTL devices. For one - there's a jumper that allows selection between +3.3 or +5V. The other cool feature is that they are using the CH340 chip. I've found this to be significantly more reliable on Windows as compared to the other commonly used chip - the SiLabs CP201x. The problem with the CP201x chips is with Windows - so many times after Windows updates are applied, the drivers are replaced with a default that causes them to no longer function until the proper drivers are manually re-installed from the manufacturer's web site. That's not the case with these using the CH340. They always seem to just work. (not an issue for linux, of course)I also like the fact that these devices have clear heat shrink tubing, protecting these devices (and your computer!) from stray wires or other things that inevitably fall on them during development and prototyping.As an extra bonus, M-F jumper wires are included; great for connecting to breadboard (but note that you'll need F-F jumpers if connecting directly to something like a Raspberry Pi)Note the default jumper setting connects the Tx/Rx pins as shipped; this allows for immediate operational verification using something like putty to confirm operation using serial loopback.

CANNOT be used to program ESP32-S3-WROOM

I'll give it 5 stars since it does what it does and the mistake was on my part.Because this UART converter does not have the DTR pin exposed it cannot be used to program the ESP32-S3-WROOM chips.Also the baud rate only goes up to 230,400 and not 2,000,000 as advertised.

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

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.
