The scenario
Designing a drone flight controller PCB around an STM32F405 with integrated IMU and barometer for stable autonomous flight.
What is in this drawing
Read the decisions behind it.
01
Use shared I2C bus with pull-ups for MPU6050 and MS5611
02
Separate 5V and 3.3V regulators for clean sensor power
03
Expose motor outputs via no-connect placeholders for ESC pads
When building a compact flight controller schematic that must be readable and ready for PCB layout.
