A protective enclosure designed specifically for a single-board computer configured as a calculator provides physical security and portability. This typically involves a compact housing with openings for the display, buttons, and ports, often incorporating a custom-designed keyboard for numerical input. An example would be a 3D-printed shell fitted to a Raspberry Pi Zero W running calculator software, powered by a small battery and featuring a numerical keypad.
Such enclosures offer several advantages. They safeguard the delicate electronics from accidental damage and environmental factors like dust and moisture. Portability is significantly enhanced, allowing the device to be easily transported and used in various settings. Furthermore, a dedicated case improves the user experience by providing a more ergonomic and aesthetically pleasing interface compared to an exposed circuit board. The development of these enclosures parallels the increasing popularity of using single-board computers for specialized applications beyond their original intent, demonstrating the adaptability of these versatile devices.
