SD Card Module

  • Neil Cameron


SD (Secure Digital) cards can be used for data storage and data logging. Examples include data storage on digital cameras or mobile phones and data logging to record information from sensors. Micro SD cards can store 2GB of data and should be formatted as FAT32 (File Allocation Table) format. The micro SD card operates at 3.3V, so only micro SD card modules with a 5V to 3.3V voltage level shifter chip and a 3.3V voltage regulator can be connected to the Arduino 5V supply.
