Vdd of STM32L100C-DISCO

Posted on November 17, 2015 at 15:31

I have this board a couple of days. I am trying to blink LEDs. With green one it works fine, but with blue one it doesn't work.

I think the problem lies in the 2V VDD. LED works if it is supplied by external source. The pin state is changed according to code.

Does anybody have this board? Manual claims that VDD is 3.3V

UPD. Sorry for bothering you. It took only one day to slightly move JP2 to repair it. =))

Hi Prog,

Great to hear that you fixed your problem and update us on this regard.

You have to refer to the board's user manual in such case anyway.

Most DISCO boards run the chips at 3.0V
