Analog Transistor Experimentation Board – Renamed from BJT Transistor Experimentation Board – A reusable PCB for prototyping, experimenting with and learning analog transistor circuits. This board is designed for experimenting with NPN transistor–based amplifier and oscillator circuits without designing and manufacturing a dedicated PCB for every new circuit. Whether you’re learning transistor fundamentals, developing a small analog circuit, or testing amplifier ideas before designing a final PCB, this board provides a flexible platform for rapid experimentation. Suitable for: Students Hobbyists Makers Educational labs Analog electronics enthusiasts  New in Version 8.2 Compared to v8.1, version 8.2 adds additional footprints for: Breadboard-friendly…

Learn how transistor differential amplifiers really work – by building, measuring and experimenting. The Differential Amplifier Experimentation Board is a reusable learning platform designed for electronics hobbyists, engineering students, educators, and anyone interested in analog electronics. Rather than repeatedly wiring differential amplifiers on a breadboard, this PCB provides a structured platform where you can quickly assemble, modify and compare different circuit configurations while observing how each design choice affects the amplifier’s performance. Whether you are learning about differential pairs for the first time or preparing to understand operational amplifiers and analog integrated circuits, this board provides an excellent foundation. Features…

Learn, prototype and build permanent 555 timer circuits. The 555 Timer Experimentation Board is a flexible prototyping PCB designed for students, hobbyists, makers and engineers who want to explore everything the classic 555 timer IC can do. Instead of forcing you into a predefined circuit, every pin of the 555 is routed to its own long connection rail, giving plenty of room for building, modifying and comparing different circuit topologies. Ground rails are placed between the signal rails, providing additional component mounting space while helping reduce unwanted coupling between adjacent signals. Once a circuit has been perfected, the board can…
