Data Logging Shield for Arduino

The Data Logging Shield for Arduino is a powerful and easy-to-use expansion shield that allows Arduino boards to store data onto SD cards while keeping accurate timestamps using an onboard real-time clock (RTC). The shield supports FAT16 and FAT32 formatted SD cards , enabling efficient storage of sensor readings, monitoring data, and project logs. It includes built-in voltage level shifting circuitry to safely interface with 3.3V SD cards and prevent damage during operation. An integrated RTC module with battery backup ensures accurate timekeeping even when the Arduino board is powered off. The backup battery can maintain the clock for years, making the shield ideal for long-term logging projects. The board also includes a dedicated prototyping area for adding connectors, sensors, and custom circuitry, allowing flexible hardware expansion. It is compatible with several Arduino platforms including UNO, Leonardo, Duemilanove, Diecimila, and Mega R3 boards. This shield is widely used in environmental monitoring, industrial automation, IoT systems, and educational electronics projects.
