Memory Cards

Memory cards provide compact, removable storage that fits directly into single‑board computers, data‑loggers and sensor hubs. Their tiny form factor, microSD, SD or MMC, lets you add gigabytes of capacity without enlarging the enclosure, while speed classes indicate how quickly data can be written during high‑rate sampling or OS boot. Compatibility is handled through standard sockets or breakout boards that expose a 0.1 in header, making integration into breadboards or custom PCBs straightforward. Adapters, including USB readers, simplify transfer to a host PC for analysis or backup. Options range from modest capacities for simple logging to high‑capacity, high‑speed cards suitable for running full operating systems, offering reliable, interchangeable storage for a wide variety of embedded projects.
