Adafruit SPI Flash SD Card - XTSD 512 MB

This breakout resembles an SPI Flash storage chip but functions as an SD card in an SMT chip format. Connect it like an SD card breakout and utilize existing SD card libraries for your microcontroller.

Examples of usage include data logging in high-vibration devices or reducing size when the microcontroller provides a USB mass storage interface. Suitable for any project where card stability is crucial, or size reduction is desired.

Specifications include a 512 MB size with FAT formatting, wear leveling, and ECC calculation. It supports clock speeds up to 50 MHz with a write speed class of 8, though performance may vary with 1-bit SPI. The breakout includes a 3.3V regulator, level shifters for compatibility with 3V or 5V logic, and a pullup on CS.

Features include plug-and-play setup with SPI mode wiring and compatibility with common microcontroller SD libraries. It's a robust solution for your embedded projects requiring reliable storage in challenging environments.
