On the surface, the Raspberry Pi boards may appear like unassuming little devices. However, these beginner-friendly SBCs are fully capable of running FydeOS, Kali Linux, and a bunch of other GUI desktops. Between the industry-standard 40-pin GPIO headers and the CSI/DSI/MIPI ports, you can equip all sorts of peripherals and accessories to turn your Raspberry Pi into a force to be reckoned with.
