Applications
Key Specifications
Getting Started
To use this card, ensure your host device supports the microSDHC specification and the SD 3.01 standard for UHS-I speeds. For industrial reliability, engineers should implement power-failure protection in the filesystem (such as LittleFS or FATFS with journaling) and monitor the card health through S.M.A.R.T. attributes if supported by the host controller.
