Arduino Data Logger Shield

The Arduino Data Logger Shield is a versatile add-on designed for logging data from sensors and modules directly to an SD card. Ideal for environmental monitoring, experiments, and IoT applications, this shield makes storing and managing data simple and efficient.

Features

• SD Card Slot: Supports standard SD and microSD cards (with adapter) for data storage.
• Real-Time Clock (RTC): Includes an integrated DS1307 RTC to timestamp data accurately.
• Dedicated Headers: Pin headers for easy connection to Arduino and external modules.
• Reset Button: Convenient reset function for debugging and testing.
• Prototyping Area: Extra space for adding custom circuits or components.
• Battery Backup: Keeps the RTC running during power loss (requires CR1220 battery, not included).

Specifications

• Voltage Input: 5V (powered by Arduino).
• RTC Accuracy: ±2 minutes per month.
• SD Card Compatibility: FAT16 and FAT32 formatted cards up to 32GB.
• Dimensions: Standard Arduino shield size.
• Applications: Data logging, environmental monitoring, and IoT systems.

Pinout:

1. SD Card Interface:

   • MISO: Master In Slave Out for data transmission.
   • MOSI: Master Out Slave In for data input.
   • SCK: Serial Clock for synchronization.
   • CS: Chip Select for activating the SD card.

2. RTC Module (DS1307):

   • SDA: Serial Data Line for I2C communication.
   • SCL: Serial Clock Line for I2C communication.
   • GND: Ground connection.
   • VCC: Power supply (5V).

3. Additional Headers:

   • Analog and Digital Pins: Pass-through connections for Arduino's analog and digital I/O pins.
   • Power Pins: Access to Arduino's 5V and 3.3V pins.
