Digital circuit experiment box boasts a luxurious and stylish design. The main unit offers multiple signal sources; locking sockets; a Taiwanese-made breadboard; printed characters and wiring on the front, and components mounted on the back. All signal sources , frequency counters, and other circuits are constructed using CPLD chips and double-sided boards. All components are selected from high-quality products, enhancing the overall quality of the machine. The absence of components on the front effectively reduces and avoids the possibility of human-caused damage . Features include ease of use, durability, flexible experimental projects, and convenient completion of various digital and analog experiments. This learning machine is suitable for electronic technology teaching in universities and vocational schools.
