DFRobot Fermion Serial Data Logger V2.0 for Arduino The Fermion Serial Data Logger V2.0 is an upgraded version of the original data logger that makes storing Arduino data simpler than ever before. Unlike previous MicroSD card modules, this compact device allows you to print data directly through the serial port without writing additional code, making it perfect for students and hobbyists working on data collection projects. The logger supports TF cards up to 32GB capacity, providing enough space for long-term data storage in applications like environmental monitoring, robot debugging, or any project requiring offline data collection. With its built-in USB functionality, you can easily connect the module directly to your computer to access stored files without needing a separate card reader. This versatile microcontroller logging shield features an onboard LED indicator that visually shows when data is being written or when a new file is being created, helping you confirm that your system is working properly. The dedicated SAVE pin makes it easy to organize your data by allowing you to trigger the creation of new files at specific intervals or events. Operating across a wide temperature range from -30°C to 85°C, this TF card data logger is suitable for both indoor and outdoor projects. The module works with supply voltages from 3.3V to 5V, making it compatible with Arduino and many other microcontroller platforms. Whether you're building a weather station, monitoring plant growth, or debugging a drone, this data logger provides a simple and reliable way to capture and store your valuable data. The upgraded V2.0 version compared to V1.0 version: Supports storage in TXT and CSV file formats. Significantly improves startup time and runtime stability. Supports scheduled creation of files for more flexible storage. Added USB port to make reading files more convenient. Features Supports FAT32 file system with compatibility for TF cards up to 32GB Built-in USB 2.0 interface eliminates the need for separate card readers Visual LED indicator shows data writing status for easy monitoring Operates with supply voltage range from 3.3V to 5V for broad compatibility Low operating current of only 23mA for efficient power usage Functions across wide temperature range from -30°C to 85°C Compact dimensions of just 23.5×22.5mm for easy integration into projects DFRobot Fermion Serial Data Logger V2.0 with Arduino Connection Diagram Applications Offline data collection Capture product debug logs Robots and drones debug
