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

My original USB TTL dongle also purchased on Amazon over a year ago was apparently bad from reading reviews of that item. I decided to spend a few extra bucks and get a better version since I do a lot with routers and messing with OpenWRT. Also into Raspberry Pi now so I figured Id get a good one this time. Worked perfectly and I saved my EdgeRouterX last night. Just remember you have to cross the TXD and RXD connections for it to work. Also look on YouTube for tutorials and specifics for your model device.

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

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.

I have a pile of assorted serial adapters sitting all over the place on my workbench, and I almost never use them. Either theyre loose wires with unlabeled cables, or theyre 5v when I need 3v3, or the power is unlabeled as well! Or my workspace is so chaotic that yet another bare board is just a recipe for shorting out my computers USB port. This, however, is really the only device that I should have. It appears to be a genuine FTDI chip (0403:6001), with selectable power and logic levels. The pins are clearly labeled, and it comes with a set of Dupont wires. The whole thing is wrapped up in a plastic case that keeps it and your computer safe from the other stuff on the workbench. Lastly, LED indicators for power, RX, and TX help you to identify connection problems. I would appreciate maybe a little more shrouding around the pins and jumpers, but what Id *really* like is if all my other serial adapters turned into these.

Used it to program esp8285 that I have extracted from no-name smart outlet, now it serves better purpose as remote speaker controller.

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.

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