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

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.

Worked as described for flashing my SV-08 Printer boards. No driver or wiring issues. Just works.

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

Works well enough for casual use, but mine died after 3 months of daily software development. I wouldn't recommend it for your daily driver working with STM micros. On the other hand, these are so inexpensive, you could buy several of them for the same price as a ST-LINK/V2.

I used it to flash a STM32 controller on the Nintendo Game and Watch. It's simple, small, and works like it should. Minimal packaging but zero damage.

Doesn't work with the current ST-Link Utility (software version 4.6) or the STM32 Cube Programmer. Tested on a PCB of my own design as well as the F411RE dev board to make sure it wasn't a hardware issue. Firmware upgrade does work, but neither software connection nor connection under hardware reset functions properly.

Items like this are what make amazon is so great. This does everything an official ST-Link programming dongle does at 1/4 the cost. For a hobbyist who might never use an ST-Link programmer again, nothing can beat that.Worked with STM32CubeProgrammer.

My 8Mhz crystal was bad out of box; I replaced it and am able to pull info from it. haven't tried flashing yet but the crystal had to be replaced to get it to shake hands with lsusb.
