Cloudy case ruins the experienceItem arrived and when I took it out of the box i noticed the case was cloudy instead of clear. When I looked at the pictures here on amazon again I noticed the posted pictures were the same as my product except in person it is impossible to be certain of the pinouts. Why the manufacturer used a cloudy case instead of clear plastic is beyond my comprehension. I checked the included documentation and there was no wiring or pin out diagrams so I could tell what wires are what. I'd remove the case so I can see the labels for each connection but I'm afraid the case would crack when disassembled. I haven't tested the product yet but this is what I'd consider a major drawback of the device. If a wiring diagram was included in the documentation instead of advertising their other products I wouldn't be so critical of the item. The item may function very well but this cloudy case is just a disaster. I can not recommend this product due to aforementioned reason.1I have my doubtsWhile this device was 'easy' to set up in terms of the 'wiring', it's a major pain to set up on Windows. 7. I've tried installing and reinstalling the drivers about three times. When i insert the device into the USB port on my pc, the LED stays on for about 5 seconds and then turns off.Compare that to it connecting to my Mac, in which the LED comes on and stays on as long as the device is connected to the USB.Since I planned on using this device with my pc more than my mac, then I'm not particularly impressed that this device doesn't seem to work well. I guess I should've bought another brand instead.I gave two starts because the board does seem to work on my mac. Other than that, I'm not sure it even deserves two stars given the annoyance of dealing with the driver issues.To make matters worse, their support sucks. Getting help from them is not reliable. I'm sorry I bought this piece of crap.2Sonoff programming no problemI used this USB to TTL serial converter with test jig to program the 5 Sonoffs that I purchased. It worked perfectly every time. I had no issues using from Ubuntu Linux 16.04 LTS. There was no set up, just use the right device address and it worked. The programming was quick, simple and easy. This converter is well labeled and easy to use.5Decent price, just works, great productThis does the job, I used it to interface various GPS modules to my Windows laptop. Just plugged-and-played and worked out of the box. As others have said, the snap-on plastic case is nice but it's an awkward fit and it comes apart easily, but this is not a priority. Note if you are using a USB power meter that this uses something like 80mW of power (a lot!), but you can just measure that and subtract from the load measurement. Only complaint is they don't offer a bulk purchase option if you want 2/4+ of them.5Very useful. Supports both 5v and 3.3v.Perfect for serial console access to many of the OpenWrt, LEDE and other embedded OS router systems I use and maintain. My one minor gripe is that the cable I received with mine is not freely rearrangeable on both ends as shown in the pictures. Only on one end are all the pins freely arrangeable, but on the other end they are a solid block of four together and cannot be separated. This works, just use that end on the USB side of the connection and flip it 180* if you need to swap Tx/Rx.4Worked nicely on suse linux after bugfixI used the DSD TECH USB to TTL Serial Converter CP2102 on opensuse linux to flash tasmota to sonoff via arduino IDE. As far as the DSD CP2102 is concerned everything work perfectly. However, there is a known bug where the device is not loaded properly due to intercept by BRLTTY which prevents the device from loading as /dev/ttyUSB0. Brltty is a background process (daemon) which provides access to the Linux/Unix console (when in text mode) for a blind person using a refreshable braille display. Brltty takes control of the device and prevents it from loading properly so I just uninstalled brltty and then everything worked seamlessly with the kernel driver and the device showed up @ /dev/ttyUSB0.5Problems with High Sierra on a MacSo DSD Tech claim that this device is compatible with Mac OS.I've just spent the last three hours attempting to get the device working on 10.13.5 (High Sierra) and I'm not sure that this claim is accurate. It seems that there is some kind problem with the way in which the kext (driver) is signed that prevents it being loaded correctly into the OS. During my first installation High Sierra requested that I approve installation of a third party kext - which I duly did.On reboot of the machine I could see that there was a CP2102 USB to UART Controller installed by looking at the System Hardware report. However there was no /dev/cu device showing up in the list of available devices. I checked the list of kexts installed and sure enough there wasn't one from Silicon Labs.There are in fact a number of threads regarding the fact that the latest driver (Version 5.0) doesn't work with 10.13.x posted on the Silicon Labs support community. Unfortunately none of them seem to provide an easy solution for fixing the problem.I suspect that I may end up returning this device and purchasing an FTID converter that (hopefully) will be more compatible with Mac OS. I'd warn Mac users to beware - I consider myself fairly savvy when it comes to the workings of Mac OS and can't make it work!1Worked perfectlyBought this to try and recover a dead router. The router turned out to have hardware issues but that was no fault of this adapter. In fact, watching the CFE boot sequence is what finally proved that the hardware was to blame. Frankly, I bougt it because it was inexpensive, but devices twice the price couldn't have worked any better.I rated 4 out of 5 stars only because the little plastic case that came with it doesn't fit the device very well. Anyone using a device like this is probably less interested in aesthetics than in functionality, but it's worth mentioning.4This Little Device Is Nothing Short of AmazingI was at the end of my wits and about to smash my bricked/dead router trying to flash the firmware and reflash it multiple times with no success. Still dead. I attempted just about every possible tip and power-switch reset routines found online. No success at all.Thus guilty of "killing" my router in an attempt to replace the stock firmware with an open-source version, I finally found a back door, a header connector inside the router hidden from view, accessible only after taking the router apart. So I did take it apart. Having found this last hope of hardware revival and the complete instructions to do it, all I needed was a USB-to-TTL adapter to break into the router through this back door.Enter this DSD TECH USB-to-TTL Serial Converter CP2102 picked out of a few I found on Amazon for no other reason that it was USB to TTL.When I received it and plugged it into my Windows 10 notebook, it was not recognized. Quickly, I went to the DST website; found and downloaded the driver, and after installing it in a flash, voila! Windows found it:There it was! Windows Device Manager--> Ports (COM and LPT)-->Silicon Labs CP210x USB to UART Bridge (COM3)Follow the instructions for resuscitating my router. Connected the wires to my router as indicated: GND to GND, Rx to Rx, and Tx to Tx (no need to reverse Rx to Tx and vice versa). With this device, I busted the back door wide open, ran the necessary programs, and there it came!!! My router, through this little adaapter, was talking to me sending to my notebook all kinds of cryptic Linux status messages.Proceeded to flash my router with this device. It took all but a short two minutes to get this done. My router came back from the dead. With my DSD gadget, I now can play with my router and flash any firmware I want. What a relief.DSD, I cannot thank you enough. Your little device saved me a lot of frustration, headaches, and grief. It turned my router from a dead paper weight into a useful, powerful machine. Thank you, thank you, thank you! One of the best $7.99 investments I have made in my life.5Works great for flashing ESP8266 devicesI screw around with a lot of ESP8266 stuff (my own projects and consumer products built around Espressif's amazing little chip). Flashing used to be a pain because I would have to track down a USB-serial adapter AND a 3.3V power supply because the FTDI's 3.3V regulator didn't have the grunt to power the ESP8266 during the flashing process. That is no longer true, because this little device has enough power to run the ESP8266 without needing an external power supply. This is one that every tinkerer should have.5
