Hey guys, I had recently started working with blackpill board(stm32f401), I am programing it with USB TO UART TTL 5V 3.3V FT232RL. Can someone share resources how to implement printf for this? I recently started learning more about embedded programming, so as a beginner is it good to program with these modules or should I learn how to use ST link?

I got the solution, by following the below tutorials. First I tried implementing UART in blackpill by following tutorial for bluepill, then I followed an another discussion on digikey for printf implementation.
1) https://microcontrollerslab.com/stm32-blue-pill-uart-tutorial-polling-method/
2) https://forum.digikey.com/t/easily-use-printf-on-stm32/20157
While trying to implement this, I faced an issue where the board is not stable in bootloader mode for some reason. Might be due to my old bread board I guess, if anyone comes across such kind of issue once refer the below discussion link
