Most of today's multimedia devices have built-in memory, most often in the form of a hard disk, SSD, memory card. The device memory is a data carrier that enables the process of saving and reading a file, e.g. in cameras, portable MP3 players, cell phones and computers. What is worth emphasizing, if we need more space for our files and folders, then the built-in memory can be expanded easily and quickly. For this purpose, the most frequently chosen solution is to connect a micro SD memory card. The Raspberry Pi 4B minicomputer, like its previous generations, is standard equipped with a slot for such cards. The micro SD memory cards for Raspberry Pi 4B offered by the Botland store are available in several different capacities and data read/write speeds. Choosing the right memory card for your minicomputer is a guarantee of proper operation in any application. We offer high-quality micro SD cards for Raspberry Pi, which ensure reliable operation and a quick process of data saving and reading.
