1PCS STM32F411 Development Board V3.0 STM32F411CEU6 STM32F4 Learning Board 100MHz Clock 512kB Flash and 128kB RAM with 1 PCS ST-Link V2 (Random Color) Support for MicroPython/Programming

Got this to wrap up my gaggiuino build. This item is overpriced for sure, at ~$5 more than buying the items separately from amazon (let alone other cheaper sources), but it works and I am one big step closer to having even more amazing espresso.

very bad board. It does not even work. It looks like some one has returned it and they decided to sell it to me, It even has one of the pins soldered indicating prior usage. I do not want to return it as it is a low cost item, and the return will maybe affect my return history.

Board was delivered in time without any issues. I was looking for this model STM board in a development type format and this is what I expected. After soldering on the pin headers included, I went to load the UART driver and program code. I used the included ST-Link interface wired as determine by its Pinots. I am using Keil as the IDE, and was able to run the debug set for ST-Link. I was able to upload the program code. The only issue is I cannot get Tera Term to see the board through a Windows 10 based laptop and the USB port I have it connected to. My program printf interacts and does not show up in the terminal screen. All in all seems to work ok.

Accurate description. I will buy more from this seller

The Programmer in the pack works as far as I can tell. The processor on the Pill board does not look like a valid processor from ST.com. I can load code simple 3 line blinky program and run it. I can also step through the code with a debugger. I will be saving this board for simple for projects. See picture. Does not match the processor on the web page. The whole package was delivered when promised.
