Arduino for STM32

I now soldered all three boards with pin headers and tried all three with 4 different UART adapters - all are showing the same behaviour. So either I really got three fake modules or I am still missing something. Just to recapitulate: Connect GND between Serial adapter and blue pill Connect Rx of Se...

That is what I did and where the error shows up.

The vendor seems to be trustworthy, they are in business for a while already.

I in fact have ordered a ST Link V2, it is supposed to arrive in the next few days.

Yes, I pressed Reset every time I powered the board. For power issues I also tried to connect the USB port to a USB power plug, but it did not make a difference. Will it be different to use the 5V pin instead? I id not want to fry the A9/A10 pins with a 5V signal. My Serial adapter is switchable bet...

Hi guys, I have been programming several different Arduino and ESP MCUs in the past and only recently discovered the ST devices. I got a few STM32F103C8s and am struggling to get them to work with either Arduino IDE or PlatformIO. I am stuck already with the STM32 Cube Programmer, that cannot make a...
