Overview
This lesson explains the practical engineering idea behind STM32 vs Arduino and gives a safe starting point for real projects.
Design checklist
Check voltage, current, power loss, thermal margin, wiring, PCB layout, component tolerances and real operating conditions.
Common mistakes
Common mistakes include using ideal values only, ignoring heat, weak power supply design, poor grounding and skipping measurements under real load.
Recommended next step
Use EngiCalc calculators to estimate values, then verify the final design with datasheets and measurements.
