The Global Specialties PB-505 Deluxe Analog and Digital Design Trainer is a robust electronics trainer engineered for electronics instruction and design and is ideal for analog, digital, and microprocessor circuits. Students will learn valuable hands-on breadboarding techniques and build a solid foundation in circuit experimentation, construction, and analysis. Students can create and implement their own circuits onto the breadboard, which is removable for multiple student usage in lab settings. The PB-505 can be used to construct basic series and parallel circuits or the most complicated multi-stage microcomputer circuits, incorporating new trends in industrial technology.
