    After setting the input level to 3.3 volts, plugged into a USB port and Windows discovered it immediately. Cant get any easier than that. The serial I/O worked with ease when connected to an extrrnal device using a terminal software.

    Works as expected and meets my USB to serial UART needs.

    I have a pile of assorted serial adapters sitting all over the place on my workbench, and I almost never use them. Either theyre loose wires with unlabeled cables, or theyre 5v when I need 3v3, or the power is unlabeled as well! Or my workspace is so chaotic that yet another bare board is just a recipe for shorting out my computers USB port. This, however, is really the only device that I should have. It appears to be a genuine FTDI chip (0403:6001), with selectable power and logic levels. The pins are clearly labeled, and it comes with a set of Dupont wires. The whole thing is wrapped up in a plastic case that keeps it and your computer safe from the other stuff on the workbench. Lastly, LED indicators for power, RX, and TX help you to identify connection problems. I would appreciate maybe a little more shrouding around the pins and jumpers, but what Id *really* like is if all my other serial adapters turned into these.

    Very nice self-contained FTDI programmer. What else can I say? You download the driver, you plug it in, and it works. :-)

    This flat didn’t work at all. It was a complete waste of time and money!

    I like that it has straps for various voltage levels. It has a clear case with clearly indicated signal lines - very nice. That will come in useful. If you just plug this thing in, it will not do anything. I use other FTDI devices (including some in our designs) and they just work by plugging them in. This one requires their driver, which is fine. After installing the driver, it wants a reset - unusual but ok. I wasnt ready to reset because I was in the middle of an edit and build so wanted to wait until later. The installation then proceeded the system to crash hard, with a blue screen and all the scary trimmings. It basically reset itself in a very rude way. That really irked me. I wasnt ready to reset and to see a blue screen seconds after installation is very disconcerting. After the PC came back up, the device worked. A bit clunky but does work. Save your work and install this thing when youre ready to reset. The price is right.

    I picked this over other cables/converters mostly for the voltage selector, and it worked perfectly for my use case. I wasnt entirely sure which voltage my project required, so having a selector was great -- it also allows it to be reused for multiple projects. The cable it comes with doesnt fit all the way onto the pin header cause it seems to be getting stuck on the plastic case; but that wasnt a deal breaker for me, and my individual Dupont wires connected and pushed all the way onto the header just fine.

    Works great, very well made For those of you looking to program an arduino with this you MUST have a bootloader installed first to use this as a programmer

    I like the multi TTL levels as I have many 1.8, 3.3 and 5V devices and I can use this one adapter on them all. I also got a USB A female to Micro female so I could keep the TTL lines as short as possible.

    Wasted hours trying to use an arduino to flash tosmota on a Sonoff device (had worked before), this worked the first time. The device appears well made and it worked immediately, also no drivers required for Windows 10.

Ideal for programmers, hardware engineers and DIY User.
Compared to other USB to TTL UART adapters, this adapter not only supports 3.3V and 5V logic levels, but also adds support for 1.8V logic levels.
At the same time it is equipped with a protective plastic case, this protective plastic case can effectively prevent static interference and various short

circuits.

Important Notes
This product uses FTDI FT232RL chip by default, because of the chip out of stock, some production batches use FTDI FT232RNL model chip . Please do not worry, FT232RNL is also the chip produced by FTDI, can completely replace FT232RL. If you still care about these please contact us.
