HiLetgo ST-Link V2 Emulator Downloader Programmer STM32F103C8T6 STM8 STM32 with Cable (Random Color)

Works like it should. This is a functional clone of the STMicroelectronics ST-Link V2 device programmer / debugger. There are many out there that are indistinguishable from this one and many people have reported that they don't work. This one does work. Though "HiLetgo" is a silly company name, I've used enough of their products over the years that I've come to trust that their products will at least function. I feel I can trust their stuff when I can't be sure about things from other weird 6-8 letter, word-scramble seller names. I bought this device, received it quickly, and successfully programmed a STM32 microcontroller with it. That's all I wanted. Oh, and the price was great too.

Perfect for flashing firmware to an stm32, you just need the STM32CubeProg programming software from STMicroelectronics. No reason to spend big bucks on a programmer when this little programmer exists!

I read some complaints about this programmer not working for some people. I've purchased 2 of these over the last month and they had different silk screens on the side designating what signals were on what pins. Both programmers are recognized by ST Micro's ST-Link Utility and both had no problems updating their firmware to the latest version from ST Micro. I initially was thinking that the silk screen was wrong or that the firmware loaded at the factory mapped the signals to different pins. When my cable that I made for the first programmer did not work with the 2nd programmer I bought I decided to open up the units and see why. The 2nd programmer I purchased has an older PCB revision (D vs E) and it conveniently has the pin names silk screened on the PCB. In both cases the silk screen on the PCB matched was was printed on the outer case. Once I made a new cable for the new programmer and used the signal names to map to my mini-JTAG connector on my board the 2nd programmer worked just as expected. It's a shame that the they moved the pinout between revisions as it definitely leads to confusion and unfortunately dedicated cables for each programmer. I only used SWD communication so I did not need SWIM but I would imagine that if you follow the silk screen you should be fine. As a side note, both of these use the same processor and it's not even a ST Micro part, it's a CKS32F103C6T6

I didn't think it was working and then I realized it was entirely me that wasn't using it correctly. Works very well,is priced very well. Used it for programming new boards for some of my 3d printers, and then diagnosing why they weren't connecting by using it to program custom firmware to them. Nice little adapter. I did need to update the firmware on it to get it to work with the latest stlink software, but beyond that it was plug and play. 4 stars because it only came with 4 wires. If it'd come with a full set of 10 jumpers, it would have had 5 stars from me.

Worked fine for me using STM32CubeProgrammer on Windows 11. I was able to flash the latest binary to my NanoVNA. No issues. Didn't have to install any drivers.

Can't complain worked with the soft ware I needed

Some work, some don't. I have purchased 4 of these, 3 worked, 1 did not.

Does what I needed to do works just fine

So when I first tried to use this, and being very new to using STM32CubeIDE, I did two stupid things, I selected all unused pins as analog, and I also selected one of the STlink pins as an output. So I downloaded by program, STlink could no longer communicate to my project. So don't do the above without setting up the pins you need to use.

Perfect
