A portable logic circuit experimental platform that can be plugged in to learn, covering all needs from science popularization in primary and secondary schools to digital circuit courses in universities. It can complete classroom demonstrations or independent explorations in 10 minutes without the need for additional soldering, power supply, or software downloads. Typical experiment: Basic gate circuit: AND, OR, NOT, XOR, XOR; Combination logic: full adder, decoder, data selector; Temporal logic: RS/D/JK flip flops, shift registers, synchronous/asynchronous counters; Comprehensive project: traffic light controller, simple password lock, reaction speed tester. Applied to information technology courses in primary and secondary schools, STEAM clubs, and vocational/undergraduate "Digital Electronic Technology" experimental boxes.
