Memory

MicroSD cards provide compact, high‑capacity storage that fits easily onto single‑board computers, data‑loggers and camera modules. Their Class 10 rating ensures reliable write speeds for operating‑system images and frequent file updates, while a range of capacities lets you balance space against cost. Card readers connect directly to a PC via USB A, simplifying data transfer and backup.

EEPROM and serial flash modules add non‑volatile memory that interfaces through standard SPI buses, making them suitable for firmware, configuration tables and small‑scale data buffers. Variants support single, dual or quad‑line SPI, offering flexibility in speed and pin utilisation. PSRAM chips supply additional volatile RAM in a small package, useful when a processor’s internal memory is limited. Across these options, compatibility with common footprints, predictable performance and straightforward wiring support rapid integration into embedded, robotics or automation projects.
