    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

    Picked this up for the adjustable voltage settings as my old one only supported 5v. I used this to flash Tasmota onto a Sonoff S31(ESP8266) and it worked perfectly. It is compatible with Linux and worked as-is without installing new drivers.

    I found this device after enormous tries and failures to identify a product that will meet my needs. Purchased a dozen of these and all are working well in a harsh environment of a hot aisle Needed to do a rework to add DTR pin. It was easy to work with material and the cover.

    Its a cheap, well made FTDI programmer that can do 1.8v logic. Im not sure what else to say, if you need something that does that thing, get this thing.

    Sometimes I run into issues where certain adapters just wont communicate properly with a chip Im trying to program. So I ordered this one to attempt to fix an issue I was having programming another chip and this one worked the first time beautifully.

    Works well right out of the box. No issue for Arduino on MacBook Pro to detect the serial port and communicate with the target board. A connector is provided for simple loop-back tests to verify everything works fine. Make sure to connect GND to the target board, otherwise the link is not stable. Dont waste time and money to try other USB-serial adaptors. This one works!

    Works great. Both 5v and 3.3V

    If you need to fix a bad flash on a FPV Reciever , like Express LRS 2.4 Ep1 Or Ep2 recievers, this will work. I used it to correct a bad firmware flash on a Happymodel EP1 2.4ghz reciever.

    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.

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.
