Product Description
Product Description
The DFRobot Gravity: Serial Data Logger V2.0 for Arduino is a compact serial data logger module for recording measurement and process data through a serial interface. Compared with solutions based on external MicroSD or TF cards, this module uses integrated 128 MB flash memory, so no separate storage card is required.
The V2.0 version supports TXT and CSV file formats and allows stored files to be read directly through the integrated USB port. A status LED provides visual indication of write activity, and the SAVE button can be used to store data in separate files. The module is intended for Arduino applications and can be connected directly to a PC without a card reader.
