Features
- Designed for Arduino Nano and Arduino Micro development boards.
- Supports FAT16 and FAT32 formatted MicroSD cards.
- Integrated Real-Time Clock (RTC) for accurate timestamping.
- RTC continues operating using a backup battery when main power is removed.
- Built-in 3.3V voltage regulator for stable SD card operation.
- 3.3V logic level shifting protects the MicroSD card interface.
- Prototyping area for adding custom sensors and circuits.
- Compatible with Arduino SD and RTC libraries.
- Includes example code for quick project development.
- Ideal for long-term unattended data logging applications.
Principle of Operation
The Arduino collects measurements from connected sensors and stores the data as text or CSV files on the MicroSD card through the SPI interface. The integrated RTC provides the current date and time for every recorded entry, ensuring each measurement is accurately timestamped.
The onboard backup battery keeps the RTC running even when the Arduino is powered off, preventing time loss between recording sessions. The integrated voltage regulator and level-shifting circuitry protect the MicroSD card while providing reliable operation during continuous logging.
Applications
- Environmental data logging
- Weather stations
- Industrial monitoring
- IoT sensor nodes
- Temperature and humidity recording
- Energy monitoring systems
- Scientific experiments
- Agricultural monitoring
- Long-term data acquisition
- Arduino educational projects
Pinout
Wiring
The shield plugs directly onto an Arduino Nano or Arduino Micro without additional wiring. Communication with the MicroSD card uses the SPI interface, while the RTC communicates over the I²C bus.
