Arduino Shield - Logging Recorder Data Logger Module V1.0 - With Battery

Description

An easy-to-use Arduino shield for time-stamped data logging via SD card. Compatible with Arduino Uno, Mega, Leonardo and similar (Mega/ADK R3 and above). Pair it with an Arduino Uno board or Arduino Mega 2560 board to start logging sensor data right away.

Key Features

• Real-Time Clock (RTC module for Arduino) with CR1220 backup battery, maintains accurate timestamps even when power is off
• SD card storage interface (FAT16/FAT32 up to 32GB)
• Built-in 3.3V level shifter for SD card protection
• Onboard 3.3V voltage regulator
• Prototyping area for custom sensor and circuit connections — pairs well with our Arduino sensor kit for environmental monitoring projects
• Includes Arduino sample libraries and example sketches

Frequently Asked Questions

How long does the RTC backup battery last?

The included CR1220 battery keeps the real-time clock running accurately for up to 2 years, even when the shield isn't powered by the Arduino.

What size SD card can I use with this data logger shield?

It supports SD/SDHC cards up to 32GB, formatted as FAT16 or FAT32.

Is this shield compatible with Arduino Mega?

Yes, it works with Mega R3 and later. Earlier Mega/ADK R2 boards or earlier are not compatible.

Do I need to write my own code to log data with timestamps?

No — the shield includes sample Arduino libraries and example sketches to get timestamped SD card logging working out of the box.
