Power management on stm32 blue pill
Posted: Fri Aug 12, 2022 7:16 am
Hello everybody,
I have been making projects with various microcontrollers for a few years. Up until now I had been using a latching circuit (taken from the arduino forum) which works for microcontrollers working at 5v. From this I started designing a circuit for the blue pill STM32 to power it with a Li-Ion battery. Below is my circuit. The MOSFET would allow me to manage the power supply for the step-up module which would power the microcontroller at 5v.
Unfortunately testing it doesn't work. I would like to ask you for advice to be able to make it work.
