Got my MCUs up and Running
I plugged this in to my USB hub and to my surprise Windows 10 recognized it immediately and I was ready to go. For me it came up as COM8 and was recognized by my programming software.I don't have a lot of RS232 or RS485 stuff these days but what I do have is a box full of these STM32 microcontrollers that require a separate UART to program. I wasn't even sure what I need to do that but this WHDTS CP2102 is exactly what I needed to get these MCUs up and running.Here is what I did. First, I followed the provided instructions and set the dip and toggle switches. I needed TLL so for me dip 1 was on (left) and dip 2 was off (right) while the toggle was down (with the usb to the left). I used the included jumpers to connect the 3v3 and ground pins the STM32F103s 3v3 and ground pins. Then I connected the RX pin on the CP2102 to my STM A9 pin and the TX to A10.I hit the reset and then opened the Arduino IDE. There I picked my board and port COM8 and set the Upload method to Serial. I opened the trusty blinky and wrote it to the board. Success!It couldn't have been easier thanks to my CP2102.

A very handy little converter
I have this converter mainly to connect a PC to anything that uses serial RS232. But what I like most is that it can also do TTL, 485, and any combination of which. So I can easily switch between the different interfaces by changing the slide switch and dip switches when I need to. It also comes with the 10 conductor cable which make it very flexible to connect to anything. Getting back to my experience. I set the switches to RS-232 and plugged into my PC. The description doesn't say anything about Windows 10, but it does work with it. As soon as I plugged it in, Windows found it. I did have to download a driver from Silicon Labs, but that's no biggie. After driver installation, I was able to configure the COM number and other settings normally found in a Windows serial port. Overall, I'm very happy with it and look forward to using it on my many projects.

Excellent functionality
This is the best USB to serial dongle I've used. It not only works as a standard USB to serial (RS-232), but also as USB to serial (TTL, 5V/3.3V), USB to serial (RS-485), AND it has 5V and 3.3V pins on its dual row header that I can use to supply Power to my test board. I'm designing a communications interface for an industrial equipment that uses RS-485 and this little guy has saved my life. A must have, IMHO.
