A portable "integrated electrical and electronic laboratory" designed specifically for training in universities, vocational schools, and enterprises. Users do not need to purchase additional power supplies, signal sources, or instruments, and can conduct experiments from basic circuits to comprehensive system levels right out of the box. The bread board and mesh board have dual areas, which can simultaneously meet two teaching scenarios: "rapid prototyping" and "real electrical wiring". Typical experiments: Ohm's law, Kirchhoff verification, RC/RL transient, transistor amplification; Gate circuit, combinational logic, counter, 555 time base, stepper motor drive; Relay control, three-phase indicator light simulation, fuse characteristics, LED driver power debugging; Boost circuit, simple inverter, STM32 minimum system power supply and debugging.
