Drone ESE Circuit Design


i want to create drone ese circuit
I've made a plan, and started work on it.
Define drone specs
Pick ESC topology
Start with schematic blocks
Create only the main empty schematic blocks for an automotive stepper valve controller.
Blocks:
  1. Power input
  2. 5V regulator
  3. 3.3V regulator
  4. STM32 microcontroller
  5. Stepper motor driver
  6. NTC temperature input
  7. I2C display connector
  8. Rotary encoder connector
  9. 24 pin main connector
Do not select components yet.
Do not wire anything yet.
Only create labeled block
