Hi, I'm doing a low-power project using the STMF401CCUx MCU.  I require only 1 I2C, 1 SPI, 1 GPIO Interrupt, and 2 GPIO input pins.    I won't be using any ADC or DAC parts, so is it fine to leave the VREF+ pin unconnected?  Does it source any curren...

Hi, I'm designing a low power tilt and shake detection sensor module using the STM32 blue pill board. I'm trying my best to attain the datasheet values of 2-5µA. I have done the following:1) Set all GPIO pins to Analog 2) Disabled all peripherals man...
