a new Arduino NANO shield，You can get going quickly – saving data to files on any FAT16 or FAT32 formatted SD card, to be read by any plotting, spreadsheet or analysis program.
The included Real Time Clock timestamps all your data with the current time so that you know precisely what happened when!
Please note that this item does not come with an Arduino NANO (you’ll need one to use with the shield), or an SD card. It does NOT come with the RTC battery.
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. The battery backup lasts for years
Prototyping area for soldering connectors, circuitry or sensors.
The onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run
Works with Arduino NANO or MICRO
