Nowadays Raspberry Pi is a tiny and most affordable computer, which you can use to learn programming through fun, practical projects. But this tiny computer is not project-board or vero-board compatible. Thus wiring with this tiny computer pin with other circuity is a risk of short-circuit, which can damage the computer.
Using this “Raspberry Pi Multifunctional Cascade Expansion Board”, you can able to access all the I/O pins using the on-board terminal blocks. This push-to-release terminal block connector is easy to access. Even no project board or vero-board is required for wiring with the other external circuity. You can directly put your connector or wire into the terminal block by simply pressing it.
