    Works great. Both 5v and 3.3V

    This is a useful little tool to flash firmwares on other devices. I personally will be playing around with mac addresses on my old network cards. I will report back if I manage to break this; but for now its working as intended. This is a specialized device; its not for those who dont understand programming or debugging or SPI / TTL interfaces.

    Simply a cut above the typical red bare pcb ones you see in so many tutorials. Used it once so far to flash tasmota onto a knock off sonoff 4 relay board, worked great. The case, options, harness etc makes this one the ftdi adapter to get IMO.

    Using this to program my Arduino. It looks solidly built, I like that it has a 3.3 and 5V option. While not the cheapest of these serial modules, it looks like a high quality and the couple of extra dollars seem to be worth it. One thing that is really wrong with it is the wire colors. Normally youd have red for positive and black for negative. Because the ribbon cable color scheme does not correspond with the power pins, inserting the cable one way and positive is white and negative is red. Inserting the cable the other way the and positive is orange and negative is green. This is a disaster waiting to happen. Because of the color confusion and the fact that you can put the cable in either way, i deducted 1 star

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

    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.

    No hassle plugged right in win11 ready to use.

    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.

    Does 1.8-5v, flow control as well as and is quite handy if you have to deal with rs232/UART often, or even occasionally. True FTDI chipset, no driver issues, just plug it in, and it works. Highly recommend to anyone in need of such a tool :)

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.
