Practical electronics engineering guides
— from PCB power integrity and grounding to embedded timing design and test equipment. Every article is built around real hardware and real measurements.

Power Integrity
Learn how to design a clean, stable PCB power supply section: regulator selection, decoupling, and layout practices that prevent noise from reaching your circuits.

임베디드 시스템
Real-world embedded design: multicore architecture on NXP MPC5748G and a high-speed LED strobe controller built with MCU + CPLD timing.

Grounding, EMI & Signal Integrity
Ground design, ground bounce, and EMI control — the invisible half of every working board.
