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

After purchasing (and subsequently returning) a similar product from another seller which didn't work, I bought this one, and I can confirm that it works for programming Blue Pill dev boards.

Worked perfectly, easy to understand and plug in to what you need to program. Computer recognizes it right away as an ST-Link programmer device, integrates seamlessly with STM32CubeIDE

No issues using this little guy to flash custom firmware on a Ninebot G30P. The thing's solid and cheap. Would recommend.

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.

Does what it says on the tin. I used this to pull the firmware from a keyboard and reverse engineer it. Yeah, it's not a Lauterbach, but it doesn't cost the same as a Power Debug Pro, either. And it's small enough to tote around in your bag and not even notice it's there. SWD connectivity works great with STM's software.

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

There's not really a whole lot of options in this space, so you're probably just going to end up getting this. It's kind of lame that you don't get to pick a color, but it's also cheap and it does the job regardless. I do wish the cables it comes with were longer. Trying to balance my laptop where the cables could reach inside my SV08 printer may have led to me dropping my laptop and permanently destroying it.

Worked to reflash my SV08. Price seemed decent. Quality seems reasonable. It was easy to use.

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
