Your question is STM Board Design. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about your experience with STM board design and everything around it.
Discuss a practical board design from requirements through schematic capture, PCB layout, bring-up, firmware, debugging, production programming, and security. Cover how you select the STM32 device and peripherals, validate power and signal integrity, protect firmware and keys, and diagnose hardware or software failures. Explain the tools, design trade-offs, verification evidence, and lessons learned from a representative project.
