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

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.

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.

Works as intended. The quality of the pcb and soldering were decent on this. Case is pretty solid. Did some firmware flashing and had no problems using this. The drivers are available on their website.

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 bought this after my prior (allegedgely 3.3V) serial cable stopped working after being connected to a 3.3V system. This is very nicely made -- its enclosed in a clear enclosure (no worries about stray wires shorting out while tinkering) and lets you select 1.8, 3.3, or 5V out (no 2.5, though DSD has another unit that adds 2.5V as well.) A cable is inclued that connects to the I/O header on the end of the USB adapter that is terminated in 1x1 female header pins -- its about a foot long. While Im not a fan of blinky lights, at least youll know this adapter is working. Ive had no issues working with a Raspberry Pi as a console cable and also programmed a 2.5V arduino-type microcontroller successfully. I use Linux and no drivers were required out of the box, just plug an play.

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

It worked well for my full semester and stopped working at the end of the semester. But worked perfectly well.

This is the perfect solution. Perfect amount of features, very rugged and overall a perfect solution. Would buy again if I needed another.

Works very well to flash my Sonoff SV. The build quality of the device is great

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