Combined PWM mode

Hi,I'm using the combined pwm mode using STM32L431 TIM2 and noticed this information in the reference manual RM0394, page 845."When a given channel is used as combined PWM channel, its secondary channel must be configured in the opposite PWM mode (fo...

NUCLEO-F411RE will not work with External 3V3 Source.

I am trying to evaluate the low-power capabilities of the STM32F411 using the Nucleo Dev Kit. I have used a simple code provided in STM SDK to toggle LED 2 at 1 second interval. LED will toggle when the board is powered by on-board USB, or 5V at VIN....
