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

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

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.

Works as advertised. I use to connect up and flash Tasmota in devices.

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

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.

There are a lot of serial to usb adapters on the market, but I really like this one and have purchased several of them for use at home and at work. The ability to select several different voltages for the interface using a jumper allows you to use the device in various situations. Very nice physical presentation and easy to configure and use. Highly recommended.

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.

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.

The adapter works well. I used it to program an ESP32-WROOM-32D module via UART. The ability to select voltage is nice.

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.
