Thanks for the answers

Hello, i've got a question: where can i set the clock configuration on 115200 or its automatically set? Cause i want to use UART for communication with tfmini plus sensor.

Thanks for the answer, i've already checked and it wont work unluckly :/

Okey, but can i find somewhere the package with this board to use it or it's the only one?

Hello, i just want to know if its possible to use the arduino program for a board that has other serial number like stm32f411E-DISCO by using this type stm32f407G-DISC1 ?
