Adafruit Data Logging Shield for Arduino
Overview
The Adafruit 1141 is a dedicated data logging shield designed to add reliable storage and precise timekeeping to Arduino-based projects. It features a standard SD card slot for high-capacity storage and a battery-backed real-time clock (RTC) for timestamping data. This shield simplifies the process of recording sensor readings or system events over extended periods without losing timing during power cycles.
Why Choose This Part
The shield integrates a level shifter for the SD card, ensuring 5V Arduino boards do not damage 3.3V SD media. It includes a prototyping area for soldering sensors directly to the shield, and the onboard RTC keeps time for years even when the main microcontroller is disconnected from power.
Applications
Getting Started
Plug the shield into an Arduino Uno or Mega and install the SD and RTClib libraries through the Arduino Library Manager. Ensure a CR1220 coin cell is installed in the RTC holder to maintain timekeeping functionality. Use the SPI interface for SD card communication and the I2C interface for the RTC.
