SKU: TH2100
This SMT-style SD storage chip behaves like a standard 4 GB SD card while eliminating removable media, making it ideal for compact and high-vibration embedded designs. It works with existing Arduino and CircuitPython SD libraries and handles wear leveling and ECC internally for reliable data logging.
Quick SpecsThis Adafruit XTSD SPI Flash SD Card breakout board features a unique SD card implemented in an SMT chip format, offering the convenience of standard SD storage without a removable card. Although it looks like an SPI Flash chip, it behaves exactly like a 4 GB FAT-formatted SD card and works seamlessly with existing SD libraries in Arduino and CircuitPython.
Ideal for compact or high-vibration designs, this solution eliminates loose connectors while providing built-in wear leveling and ECC handled internally by the chip. The breakout is preconfigured for SPI mode and includes a 3.3 V regulator, level shifting for 3 V or 5 V logic, and a CS pull-up, making it quick to wire and easy to integrate into data logging, embedded storage, or USB mass-storage projects.
