Item works as intended. SPI flashing no issue with correct voltage. Hope it lasts for a while.

A handy little gadget, which works fine with Windows and Linux. The transmit and receive LEDs are a useful feature, as is the switch to select 5V or 3.3V.

I've got a Seeeduino Ethernet MCU that requires a USB to TTL adapter in order to upload sketces to it.Having purchased a multi-pak of cheapies to use in collecting data from some Arduinos, I assumed they would work for this application, and I was wrong. I spent quite a bit of time trying to get to get the cheap converter(s) working (tried a couple of them), but no luck.Since at this point I really had no way of knowiing for sure if it was the converters or the board that was faulty, I searched for the cheapest converter with the best reviews, and found this one. It helped that it was available with one day delivery.As another reviewer pointed put, the soldering quality is pretty sub-standard, and I figured I just threw $10 away. I needed to use the DTR function, so soldered a header in place, and connected it to the MCU and my PC. The power light came on on the adapter and the MCU, so that was a good sign.Upon opening the IDE and clicking the upload button, I was very happy to see the red and green winky-blinks light up as the sketch uploaded without issue.So bottom line is that the unit works fine, but is slightly to the shabby side of quality.

I used this adapter to flash Tasmota onto some Sonoff plugs. It worked flawlessly and was very easy to use.A word of caution - be sure to choose the correct voltage on the board (3.3V or 5V) before using!

No problems using this. Flashed a couple of Sonoff devices and worked w/o a hitch. A bit stiff to get in and out of the USB port (due to no case) but I was being overly careful not to damage the board. Good product.

Good versatile usb-to-uart interface. Works on 3.3v fine, didnt test 5v. Durable and well-built.PS: for beginners: RX on the programmer goes to TX on the device, and TX on programmer goes to RX on device. I got this wrong in the beginning and was trying to figure out why it wasnt working. This isnt a mistake, this is how serial is designed (RX is recieve, and TX is transmit, so transmit of one has to go to recieve of the other).

Es funktioniert sehr gut, ich benutze es selbst, um Sonoff-Geräte zu programmieren.

Dopo avere perso parecchie ore/giorni per identificare un malfunzionamento di una apparecchiatura da me realizzata, che usava una schedina cinese low cost dichiarata FTDI232 compatibile, che si verificava senza un preciso schema temporale, ho avuto il sospetto che potesse esserne quella la causa. Sostituita con questa "originale", tutto si è messo a funzionare senza intoppi. Morale della favola: non è tutto oro quello che luccica e se dovete realizzare qualcosa di affidabile, usate prodotti di qualità come questo. Non fate come me, che per risparmiare qualche euro ne ho buttati via moltissimi di più in tempo e tribolazioni.

If I could give it more than 5 stars I would. If you've used dodgy FTDI programmers or home grown ones you know what a pain they can be. Intermittent usability, incorrectly labeled pins, etc - you know the pain. If you don't know the pain, avoid it, and get this programmer. It's awesome and will save you hours of headaches fighting to program your device (when that time can be spent developing and deploying your code). This device is quality, that's first and foremost - it just looks and feels well made. Second, the pins are gold plated and sturdy. The would need to be if you're constantly plugging wires in/out of it. Also the pins are clearly labeled and large enough that you can read it (seems insignificant but this is important to me - I don't like ambiguity as that can lead to destroying the device you're trying to program).With this programmer, I don't have to fiddle with constantly plugging it in and out to *try* and get it to sync to my device. It just works (just make sure you set the vcc voltage to match your device requirements).

Appears to be a rock-solid FTDI chip.Automatically detected by both my Windoze 10 and MacOS 10.12 systems.The supplied little jumper shown in the pictures installed between TXD&RXD is there to check loopback.If your terminal program echoes what you type through its assigned virtual serial port, it’s working properly.Obviously, remove before actual use.Perfect for use for its advertised purpose: a general-purpose firmware loader.However,If your primary use is with Arduino platforms that do not feature their own USB(eg. Arduino Pro Mini and clones, and others):it works fine, with the Arduino IDE & avrdude, *if* you keep in mind:1. You’ll have to rearrange the order of the pins into the Arduino, as this unit does not follow the “standard” Arduino FTDI pinout ordering.2. You’ll have to run a extra (preferably green) wire between the unit’s pad labeled “DTR#” and the Arduino’s DTR pin.I soldered a long right-angle pin to the unit’s DTR# pad and created a rearranged female-female 6-conductor cable,observing the “standard” FTDI “green/black” wire color & ordering to minimize the probability of connecting it backwards.Again, if your primary application is Arduino FTDI, there are other, smaller, cheaper, standard-wired, genuine FTDI adapters out there.Nevertheless, I kinda like this one.It’s one of the few FTDI-based adapters to feature a USB Type A” connector, useful if you want to to plug it into your laptop without a USB cable.One nitpick: I would have liked to see a schematic somewhere online, but have not found one, yet.Still, does what it claims, so 5 stars!----

Product came neatly packaged in an anti-static pouch and also included 10 dupont female-female header cables. The product was immediately recognized in Ubuntu as well as Windows 10 without having to hunt for drivers. It has a built-in 3.3V and 5V switch depending on the device you want to connect it to. The product was shipped with a jumper between TX and RX pins. I do not know what that was for, and have stashed it If i have a need for it in the future. There are LEDs to indicate transmission and reception of data. Similar devices have issues where the USB port is not soldered on to the board securely. This board has two additional solders at the end to reinforce the USB connector. It feels very solid. However, I would use extreme caution or use a USB extender cable to prevent wear and tear on the device. I used it to flash Tasmota firmware to Sonoff switches and the process went of without any hitch. Highly recommend the product for such a purpose.
