The Gravity: Serial Data Logger V2.0 offers a smarter, more efficient way to handle offline data logging for your Arduino projects. Unlike traditional MicroSD card modules, this upgraded serial data logger provides onboard 128MB Flash memory and direct USB access, eliminating the need for external TF cards or card readers. This makes it a more reliable Arduino data logger solution compared to a standard MicroSD card module for long-term monitoring. With serial port data printing, no additional code is required—simply connect and log with this plug-and-play serial data logger. The built-in SAVE button allows you to create separate files on the fly, and the LED indicator gives real-time feedback on data writing status. Supporting both TXT and CSV formats, this USB data logger is perfect for collecting structured data from sensors, robots, drones, or any embedded systems. Using an Arduino data logger has never been easier for developers seeking a compact USB data logger. Key Features 128MB onboard Flash storage—no TF card needed for this serial data logger USB 2.0 interface—direct file access without card reader on your USB data logger Serial communication—plug-and-play with Arduino data logger systems Supports TXT and CSV file formats for easy analysis Multiple baud rate support for wide compatibility with MicroSD card module alternatives LED indicator shows active data writing status for the Arduino data logger Scheduled file creation for flexible data management in your serial data logger Built-in SAVE button to store data in separate files on the USB data logger Applications Offline data collection in field environments using a serial data logger Debugging robots and drones with a compact Arduino data logger Product log capturing and testing via USB data logger interface Environmental monitoring projects with long-term serial data logger storage Sensor-based experiments requiring a robust Arduino data logger Specifications Operating Voltage: 3.3V–5V Operating Current: 10mA USB Protocol: USB 2.0 for fast data access Operating Temperature: -20°C to 65°C Humidity Range: 5%RH to 85%RH Dimensions: 32 x 27 mm (1.26 x 1.06 inches) What’s in the Box 1 x Gravity: Serial Data Logger V2.0 1 x 2.54-10P Black Single-row Connector 1 x Gravity-4P I2C/UART Sensor Cable
