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.

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.

I’m still learning but this has been an asset when needed. Would buy it again.

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

This seems to be a legit FTDI chip. It passes the checks by the FTDI programming software.

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

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

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.

Works great. Both 5v and 3.3V

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.
