A digital and analog trainer kit is a fundamental requirement for electronics education. Engineering students must understand both analog signal behavior and digital logic systems to build real-world electronic products. However, learning these concepts without proper laboratory hardware often limits practical understanding.
This Digital and Analog Trainer Kit is designed as a complete laboratory platform, combining power supplies, signal generation, logic testing, and project development space on a single board.
