Most contemporary computers and RTV devices have integrated memory, usually in the form of a hard disk or solid-state. The device memory is a data carrier that allows storing and reading a file, e.g. in cameras, portable music players, cell phones, computers and music synthesizers. The standard built-in memory can be easily and quickly expanded if we need more space for our files. For this purpose, the micro SD memory card is most often used. Like previous generations, the Raspberry Pi 3B + mini computer comes standard with a slot for such cards. Botland Store micro SD memory cards for Raspberry Pi 4B are available in various capacities and speed classes. Choosing the right memory card for your mini computer is a guarantee of proper operation in any application. For Raspberry Pi, we offer high-quality micro SD cards that ensure reliable operation and fast data storage and reading process.
