DataLog Shield for Arduino – Log Sensor Data to SD Card with Accurate Timekeeping

Expansion Module with SD Card Interface, Built-in RTC and Prototyping Area for Sensors

The DataLog Shield is your reliable partner for any project requiring data recording and analysis! This expansion board, compatible with Arduino UNO, Leonardo, Mega, and others, allows you to easily store information from sensors on a standard SD card. Thanks to the built-in Real Time Clock (RTC) with a backup battery, every measurement is timestamped accurately, even when the main power is off. The module also includes a 3.3V regulator for stable power and SD card protection, as well as a convenient prototyping area for directly soldering your sensors or circuits. Perfect for learning, experimenting, and serious IoT applications such as weather stations, monitoring systems, or environmental analysis. Start logging data easily and professionally with the DataLog Shield!

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 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.
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 UNO,  Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher.
ADK/Mega R2 or lower are not supported.
