❓ Frequently Asked Questions
What is circuit design?
Circuit design is the process of planning electronic circuits to meet requirements: select components, draw schematics, simulate behavior, lay out PCB traces, and verify the design works.
What is an embedded system?
An embedded system is a computer inside a device that performs a dedicated task, often with real-time constraints and sensors/actuators.
What is the difference between a microcontroller and a microprocessor?
A microcontroller includes CPU, memory, and peripherals on one chip for compact, low-power tasks; a microprocessor is just the CPU and needs external memory and peripherals for larger, flexible computing.
What is a PCB and why is layout important?
A PCB (printed circuit board) provides physical support and electrical connections via traces; good layout is crucial for signal integrity, power delivery, and thermal management.
What are common serial interfaces used in embedded designs?
Common interfaces include UART (asynchronous), SPI, and I2C; other possibilities are CAN and USB for broader connectivity.
