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 version provides onboard 128MB Flash memory and direct USB access, eliminating the need for external TF cards or card readers.
With serial port data printing, no additional code is required—simply connect and log. 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 logger is perfect for collecting structured data from sensors, robots, drones, or any embedded systems.
