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

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.

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

At first it didnt recognize the port I used to plug it in. I solved it by moving to another port. Once I got that corrected, it worked as advertised.

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

Great housing, protects the PC board...excellent!

Works as expected and meets my USB to serial UART needs.

Overall I’m really happy with this device. The voltage switching jumper is a great addition to have and has come in handy more than I would have expected when poking around.

Wasted hours trying to use an arduino to flash tosmota on a Sonoff device (had worked before), this worked the first time. The device appears well made and it worked immediately, also no drivers required for Windows 10.

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

After setting the input level to 3.3 volts, plugged into a USB port and Windows discovered it immediately. Cant get any easier than that. The serial I/O worked with ease when connected to an extrrnal device using a terminal software.
