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

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.

Works perfectly with a Nextion 3.2” display. Don’t usually need products like these so can’t say for sure but it seems like a great value for a little more that $10

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.

Worked like a charm to update firmware on a telemetry radio set

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.

Works prefect for flashing my GPS modules on my FPV drones.

Made it easy to connect to serial port header of old wifi router, which allowed me to load open-source firmware (dd-wrt) onto it.

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 is a useful little tool to flash firmwares on other devices. I personally will be playing around with mac addresses on my old network cards. I will report back if I manage to break this; but for now its working as intended. This is a specialized device; its not for those who dont understand programming or debugging or SPI / TTL interfaces.

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.
