Programming a STM32F103C8T6 (blue pill) dev. board

Not open for further replies.


Hi guys, I have bought a blue pill board (an STMF103C8T6) development board and tried programming it. I am using the FTDI chip (board) to transfer code from Arduino IDE (on a Mac) to this board. But I am unable to send code to it.

I accidentally connected a micro-usb cable to power given on the board and connected the 3.3v and GND from the FTDI board to the STM32 blue pill board at the same time. Is there a chance that I might have blown my board up? The power LED works fine and the PC13 green led blinks. So what is the problem and why am I not able to upload code? Is it because I am using Mac or anything else?

Thank you
