Was detected out of the box in Ubuntu 15.04; and worked great with Minicom (/dev/USBtty0).
Windows 10 did not automatically install the drivers, however allowing it to check Windows Update found the driver and installed without issue. Shows up in Windows as "Silicon Labs CP210x USB to UART Bridge". Worked just fine with puTTY.
Do wish there was a case to buy for this (there seems to be something close on Thingiverse to 3D print), but at this price I just bought a second one as a backup just in case I happened to fry the one.
Mine came with rainbow colored wires which was a nice touch.
Ordered from uxcell which offered Prime Shipping, so was received quickly.
I ended up getting two of these and setting up one to be 5V only and the other 3.3V only. I covered them in clear shrink wrap and labeled each for its voltage. At this price, why not have two and this way I'm a little less likely to ruin a 3.3V board by feeding it 5V.
Anyways, these are among the good ones.
Working with ESP8266-01-12's I needed something to hook up to use the various tools for ESPs from the Espressif SDK to the ESPPlorer application, this USB to TTL converter easily setup as a COM port in Windows 7 which allowed me to connect to my ESP's.
As a side-note, I also picked up a genuine FTDI USB to TTL at the same time, and while this unit works great I do tend to use the other one ONLY because of the microUSB jack it hosts. Don't get me wrong, I purchased a USB extension (USB A female to USB a male) so I could get more extension on this unit and it works but having the ability of microUSB cable, which I tend to have connected for charging phones/etc; it just gets used more. Had this unit been able to utilize microUSB, I would have zero issue with this breakout. The CP2102 UART works great and as long as you download the proper drivers and install PRIOR to inserting this; you'll have no issues [caveat because not all users systems are the same].
The price is right, the job is easy and this little device gets it done.
I've tested my ttl adapter with both a first gen Raspberry PI model B and a c.h.i.p. (next co thing) and I was able to interact with both just fine. I have only used 115200bps and 8n1. I really like that they include a breakout for almost every pin that that cp2102 has. I looked through the data sheet and just about the only pins that don't expose are the raw usb pins!
My only nitpicky complaint is around the included cable. Mainly that it does not have the more common colors that you see with a uart/ttl adapter (black white green red) the one that came in my bag was gray, red, orange, yellow, green. It's also only 5 wires but there are 6 pins with that said I would not expect someone to need both +5 and +3.3.
One thing to keep in mind about the +3.3v pin is a max current of 100mA so if you do want to power something with the Cp2102 you need to make sure it's a low draw.
Update: HiLetgo was very helpful and sent me an older Silicon Lab driver and encouraged me to retry. I did and tried everything but this adapter did not work for me. I changed my rating based on the reseller customer service. Hopefully this adapter works for somebody else.
One very nice feature is that in addition to the JST connector, there are also breadboard connections for all the relevant outputs (including some that aren't on the JST). The breadboard has the following leads:
I used this as a serial cable for my Linksys WRT1900AC router, and it worked great. I am using Mac OS X Yosemite, and the free drivers from Silicon Labs worked fine after installation.
