HALJIA Logging Recorder shield Data Logger Module Compatible with Arduino UNO SD Card

SD card interface works with FAT16 or FAT32 formatted cards. 3.3V level shifter circuitry prevents damage to your SD card. Real time clock (RTC) keeps the time going even when the Arduino is unplugged. Included libraries and example code for both SD and RTC, means you can get going quickly. Prototyping area for soldering connectors, circuitry or sensors.
