Saving data to files on any FAT16 or FAT32 formatted SD card, to be read by any plotting, spreadsheet or analysis program, included Real Time Clock timestamps all your data with the current time, so that you know precisely what happened when!
The data logger is a reliable, well-rounded and versatile design. It is easily expanded or modified and come well supported with online documentation and libraries.
- 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
- Included libraries and example code for both SD and RTC mean you can get going quickly
- Prototyping area for soldering connectors, circuitry or sensors.
- Configurable indicator leds
- Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run
