Hello,
I need to power the NucleoF103 development board using an external 3.3V power supply. I have read in the NucleoF103 manual that this is possible by removing SB2 (to disconnect the voltage regulator output) and SB12 (to disconnect NRST). I also have read the schematics of the board and it looks that the power supply for the microcontroller (VDD) is provided by 3.3V connector through the JP6 jumper. Is the same thing if I mantain SB2 connected, remove the JP6 jumper and provide the 3.3 power supply to the pin of the JP6 jumper instead of the 3.3V pin of the Arduino connector? Moreover, what is the reason for disconnecting NRST by removing SB12? I have already programmed the board using ST-Link before switching to the external 3.3V power supply. Is there any other way to proceed without removing SB12 (for example connecting T_NRST on CN4 to ground)?
Thanks.
Marco
