DSD TECH SH-U09C2 USB to TTL Adapter Built-in FTDI FT232RL IC for Debugging and Programming

Very good quality. In my opinion, the build quality of this product is better than the 20 bucks Adafruit one. And it provides 3 voltage configurations, which allows me to debug my 1.8V boards. It comes with female to female jumper wires, no need to buy wires seperately. The only caveat is that I need to purchase a USB extension cord.

No hassle plugged right in win11 ready to use.

I bought the adapter to hook up to a serial port (UART) on a ESP32 development board. Works great. I like the design of the jumper cable.

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.

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.

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.

Real FTDI FT232RL chip. Win 7 instantly recognized it and loaded the driver. Works flawlessly. Love the plastic case.

Very nice finish and it worked immediately

Works great. Both 5v and 3.3V
